What Notation Does Prolog Use For Expressing Arithmetic Operations? (Solution)

The notation for arithmetic operators was an example. Internally, Prolog will use is(11,+(2,*(3,3))), but we can write 11 is 2 + 3 * 3. Such functors that can be written in between their arguments are called infix operators.

What notation requires parentheses in order to correctly define the order of computation?

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. Given two or more operations in a single expression, the order of the letters in PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete.

What does the built in predicate cut (!) Do?

reduce possible answers of a question that is asked using the rule. What does the built-in predicate cut (!) do? Remove all existing backtracking points.

What is the main reason of applying two step translation of high level programming language?

to allow functions to return different types of values.

What parameters are required when performing file operations fread and fwrite?

What parameters are required when performing file operations fread and fwrite? The reason that we need to call fflush() or cin.

Does coding use Pemdas?

Most modern computer programming languages (probably all mainstream languages) follow the same rules for order of precedence for mathematical operations as PEMDAS, PEDMAS, BODMAS, BOMDAS, BIDMAS (they’re all the same).

How does Pemdas work in programming?

Multiplication and division come before addition and subtraction is a rule we learned in grade school. This rule still works. A common mnemonic to remember this rule is PEMDAS, or Please Excuse My Dear Aunt Sally. Precedence rules may vary from one programming language to another.

Why are cuts used in Prolog?

The cut, in Prolog, is a goal, written as!, which always succeeds, but cannot be backtracked. Cuts can be used to prevent unwanted backtracking, which could add unwanted solutions and/or space/time overhead to a query. The cut should be used sparingly.

What does + mean in Prolog?

Because of the problems of negation-as-failure, negation in Prolog is represented in modern Prolog interpreters using the symbol +, which is supposed to be a mnemonic for not provable with the standing for not and the + for provable.

What is machine code written in?

It is usually written in binary. Machine code is the lowest level of software. Other programming languages are translated into machine code so the computer can execute them.

How is a programming language translated to machine code?

A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file.

Which of the following translates all high-level instructions into machine code prior to running the program?

A compiler translates the entire program written in a high-level language to machine language prior to execution.

What is the syntax of fread?

The syntax of fread() function is as follows: Syntax: size_t fread(void *ptr, size_t size, size_t n, FILE *fp); The ptr is the starting address of the memory block where data will be stored after reading from the file.

Does fwrite write in binary?

In line 48, fwrite() function is called to write the structure variable emp into the file in binary mode.

2.3 Arithmetic in Prolog

When it comes to doing complex mathematical calculations, Prolog is not the computer language of choice. Despite this, it does have certain mathematical ability. The formula for evaluating arithmetic expressions follows a pattern (whereExpressionis some arithmetical expression) Expression8 is represented by the letter X. In this case, the value ofExpression will be assigned to the variableX. As an illustration,? – Is X equal to 10 plus 5.X equals 15? yes? – X equals 10 minus 5.X equals 5 yes?

– X equals 10 / 5.X equals 2yes?

X = twenty yes It is vital to notice that the expression itself is not evaluated.

There are several other pre-defined Prolog arithmetic infix operators.



greater than


less than


= greater than or equal to


= less than or equal to


When it comes to heavy-duty mathematics, Prolog is not the computer language of choice. Despite this, it does have some mathematical ability. In arithmetic expressions, the pattern for evaluating them is (whereExpressionis some arithmetical expression) Expression8 is represented by the letter “X.” The value ofExpression will be used to initialize the variable X. As an illustration, How much is X times five? X times ten is equal to fifteen. yes? Does the number 10 minus 5 equal 5? – Does the number X equal 10?

— 10/5 = 2Yes?

– X equals 10 + 5 * 6 / 3.X equals 20yes.

The infix operatoris/2 must be used to separate a variable from a result before collecting it.

2.3.1length/2

It is frequently beneficial to be able to compute (or double-check) the length of a list of items. This is something that we can now accomplish with the help of arithmetic operators. The starting point is the empty list, which has the obvious length of zero. As a result, we have the Prolog clause: The recursion asks us to simply add one for each item on the list, as follows: 9length(, N): 9length(, N): 9length(, N): – length(T, N1), where N is equal to N1 + 1.

2.3.2Exercises

Define the predicatesquare/2, which accepts a number as its first argument and returns the square of that number as its second argument in Exercise 10. (There will be no recursion in this one.) Define a predicatepower/3 that accepts numbers as its first and second parameters in Exercise 11. PandNand returns as the value of its third argument a number that is N to the power of P. For example,?- power of N to the power of P. (3,2,P). P = 8 (yes). Remember that this needs the use of a recursive rule as well as the use of arithmetic.

Learn Prolog Now!

Worksheet10Develop a predicatesquare/2 that accepts a number as its first argument and returns the square of that number as its second parameter. It is not necessary to use recursion in this case. Define a predicatepower/3 that accepts numbers as its first and second parameters in Exercise11.

Specifically, PandNand returns a number that is N to the power of P as the value of its third parameter. For example,?- power of PandNand (3,2,P). Eight yes votes for P. Notably, a recursive rule and the usage of arithmetic are required in order to do this.

4.1 Utility goals

Help(S) S should represent a symbolic atom, for example, help (assert). haltStops the Prolog process, allowing the operating system to restart. trace and notrace are used to turn on and off trace, respectively.

4.2 Universals

Help(S) assistance, for example, should be represented by the symbol S. (assert). stopProlog is terminated; the operating system is restarted. turn trace and turn notraceTurns on and off the trace function.

4.3 Loading Prolog programs

Help(S) S should be a symbolic atom, for example, “help” or “support” (assert). haltStops the Prolog process and restarts the operating system. trace and notrace are switches that turn on and off trace and notrace, respectively.

4.4 Arithmetic goals

NM, NM, N =M, N=M, NM, NM, NM These relationships test exactly what they appear to be testing. For these objectives to be successful or unsuccessful, M and N must obviously be tied to numerical values (and not to cause error).

4.5 Testing types

X is bonded to a symbolic atom, and Atom(X) determines if this is the case. As an illustration,?- atom (foot). – yes? – the atom (3). – atom(‘foot’) if the answer is no. – yes? – the atom (“foot”). nointeger(X)Determines whether or not X is tied to a positive integer. real(X)Determines whether or not X is associated with a real number. string(X)Determines if X is associated with a string.

4.6 Equality of Prolog expressions

Testing whether or not X and Y can be united, and whether or not they cannot, are performed. For example,?-=.X = a, Y = b, R =?-=.noX =Y, X = YTests whether X and Y are now co-bound, i.e., have been bound to or share the same value, or if they are not co-bound at this time. Take, for example,?- X = 3, Y = 1 * 3, X = Y.no?- X = a.=,X = Y.X = a, Y = a.x = a, Y = a.no?-

4.7 Control

Testing whether or not X and Y can be united, and whether or not they cannot. For example,?-=.X = a, Y = b, R =?-=.noX =Y, X = YTests whether X and Y are now co-bound, i.e., have been bound to or share the same value, or if they are not co-bound at this point. Take, for example,?- X = 3, Y = 1 * 3, X = Y.no?- X = a.=,X = Y.X = a, Y = a.x = a, Y = a.no?

4.8 Testing for variables

Ground(G) determines whether or not G contains any unbound logical variables. var(X) determines whether or not X is associated with a Prolog variable.

4.9 Assert and retract

Asserta(C) Assert clause C into the database first, followed by any subsequent clauses that share the same key predicate. It is the first predicate discovered while reading a clause from left to right that is referred to as the key predicate of the clause. invoking assertz(C), invoking invoking (C) Insert clause C into the database at the bottom of the list of clauses that have the same key predicate. retract(C) C should be removed from the database. It is necessary that C be suitably instantiated in order to identify the predicate key.

4.10 Binding a logical variable to a numeric value

X is EBinds the logical variable V to the numerical value of E. X is EBinds the logical variable V to the numerical value of E. A number or a number-valued expression with customary parentheses, such as, for example, (2*Z + W)/4* Z -W, must be used in the evaluation of the expression E.

This is assuming that Z and W are both bound to numbers at the time of evaluating the expression. ?- X equals 22, Y equals X * 3, and Z equals sqrt (Y). X equals 22. Y is equal to 66. Z is equal to 8.12404.

4.11 Negation as failure

In the case of failure, not(Q), +QNegation as failure is defined by:not(), call(),!, fail. not(Q).

4.12 Input/output

A successful Seeing(X) is one where X is (or can be) connected to the current read port. The user’s input is represented by the letter X. see(X)Opens a port for the input file that is tied to the variable X. The port from which the subsequent input for’read’ is obtained is then used. seen ‘close’ closes any specified input port or file, and causes’read’ to look at the currently selected user. read(X) Reads a Prolog type expression from the current port and stores the result in the variable X.

  1. X=user is the output port in question.
  2. The output from the ‘write’ or ‘display’ commands is transmitted to that port as well.
  3. write(E) The current output port is used to write the Prolog expression connected to E.
  4. tab(N) Write N spaces to the output port that has been selected.

4.13 Prolog terms and clauses as data

It is successful when X is (or can be) tied to the current read port, which is shown by the success of seeing(X). Input is provided using the keybord. The function see(X) opens a port for the input file that is connected to the variable X. Afterwards, that port is used to receive further input for the function’read.’ seen ‘read’ will glance at the user after closing any specified input port or file. read(X) Obtains the value of the current port’s Prolog type expression and stores it in variable X.

  1. X=user is the current output port in this case.
  2. It is this port that receives any further output from the commands ‘write’ and ‘show’.
  3. write(E) The current output port is used to write the Prolog expression connected to E that was previously specified.
  4. tab(N) Input N spaces into the output port that you’ve chosen to use.

4.14 Prolog operators

:- op :- op :- op :- op (P,T,O). Declare the existence of an operator symbol. As an illustration, consider the following example of a source program: “has color” op(500,xfx,’has color’). a contains the color red. The color of b is blue. Then.? – b has color is a color. Is C.C. equal to red? – What has the color red in it. What is equal to a Pis precedence and an integer. P with a larger size has less precedent (ability to group). The values of the precedence numbers for built-ins are determined by the Prolog system in use.

(For further information, consult the reference materials or use the help function by typing the word ‘operator’ into the search box.) This is the operator type: the nonassociative xfyinfix right-associative yfxinfix left-associative fxprefix nonassociative fyprefix right-associative the nonassociative yfpostfix left-associative the nonassociative xfyinfix right-associative the nonassociative yfpostfix left-associative The operator goes by the initials O.

Which symbols are available for use may be determined by the Prolog expression reader (i.e., which kind of Prolog you are using).

-fx;xfy,xfynotfyis, =., and so on xfx+,-yfx, fx*,/yfx, xfx+,-yfx xfysmallerPvalue To ensure that the user’s operators are read in with the correct meaning, it is sometimes necessary to exercise patience while assigning proper precedence values to the operators.

4.15 Finding all answers

Findall(Things,GoalExpression,Bag)computes all Things that satisfy the GoalExpression and collects them in the list Bag once they have been calculated. If the GoalExpression fails, the Bag will be an empty list, as seen below. If all variables in GoalExpression are existentially quantified, findall handles them as if they were. a bagof(Things,GoalExpression,Bag) is a function that computes all Things that satisfy the GoalExpression and collects them in a list Bag. If GoalExpression fails, bagof will fail as well.

See Section 2.12 for several illustrations.

The Bag will be similar to bagof, with the exception that it will not include duplicates and will be sorted.

Module 12 Project

In this PA, you will develop some analytic procedures that will be used to a data structure known as an expression tree You will work on projects that are comparable in nature in Ruby, Haskell, and Prolog, with the purpose of learning about the distinctions between the three languages. The dynamic object-oriented programming skills you will learn in Ruby will be gained through extending existing Ruby classes. You will create pattern-matching functions in Haskell in order to get experience with functional programming.

The following are the project’s starting files:p4.zip

Requirements

You may choose to disregard Lexer.hsand Parser.hs. Their backend code for parsing basic mathematical statements was built automatically from grammar specification files using a set of tools known as AlexandHappy, and they were generated from grammar specification files. Here is an example of a context-free grammar that describes the language that this parser is capable of understanding: E -int| E + E | E – E | E * E | E -int| E -int| E + E | E – E | E -int| E -int| E -int| E -int| E -int| E -int|

  • E -int|
  • E -int|
  • E -int|
  • For example, the expression(2+3)*4 will be processed into the following tree when it is evaluated: Among the datavalue constructors used to create or pattern match against an expression tree are EInt, EAdd, ESub, andEMul, which are all datavalue constructors.
  • Last line of Exprdefinition states that we want to be able convert expressions to strings and compare them using the built-in recursive definitions of Haskell.
  • This will be accomplished through the development of functions that recurse through an expression tree depending on data patterns.
  • It takes a tree and matches it against one of four distinct patterns that are conceivable using the value constructors, delivering a new kind of string for each pattern it is matched against.
  • It is necessary to provide an expression tree as the function’s input, and you must provide the output of the function for each pattern that might be matched against the input tree.
  • The functions that you must implement are described in further detail below.

You should consider what the definition of each function implies in terms of eachExprpattern while writing your code. Due to the lack of “abstract” classes in this version, you will need to define patterns for each value constructor, as opposed to the Ruby implementation.

  • When a mathematical expression is evaluated, the function Eval: Expr-Int- calculates the outcome of the evaluation. It is recommended that all operations be performed using integer arithmetic. count Expr -Int- is a function that counts the total number of arithmetic operations included in an expression. For this method, all three operations (addition, subtraction, and multiplication) are taken into consideration. expression-tree-height: The Expr -Int function calculates the height of an expression tree, where the height of a single-node tree is defined as one
  • Expr -String- is used as a postfix. This function returns a postfixstring representation that has been flattened. For example, the notation for (2+3)*4 would be “2 3 + 4 *” in postfix notation. When converting numbers to strings, you should make advantage of the showfunction. uniqInts: Expr – Retrieve a sorted list of all unique integers contained within an expression using uniqInts: Expr. A single instance of each number should exist in the resultant list

You might find it useful to build two helper functions for the last function (uniqInts), which are as follows:

  • Uniq: Eq t =- Returns a duplicate of the supplied list that has been purged of duplicates
  • Ordered copy of the specified list is returned by the sort command: Ord t.

A copy of the supplied list, with duplicates deleted, is returned by Uniq: Eq t =- Ordered duplicate of the specified list is returned by the sort command.

Submission

Your program must include the implementations that were previously mentioned. You must name your Haskell script fileP4.hs in order for it to run. You must include your name in the file as a remark at the start of the document. As is customary, breakdown your methods to make them more legible, give them descriptive names, appropriately indent them, and so forth. You will be scored somewhat on the readability of your code, but largely on whether or not it functions properly. ONLYP4.hsmust be sent to the corresponding assignment on Canvas by the due date.
