Chapter 23, Problem 23.3E

Program Plan Intro

Program Plan-

• To include header files and required namespaces.
• To define function template equalTemplate of type class.
• To define tool function isEqualTo with two values to be compare as arguments using template type EqualTemplate.
• Intiaiize the main() function.
• Prompt user to input two entities of same type.
• Call function isEqualTo to evaluate for eachtype.

Summary Introduction- This program evaluates equality of two entities using function templates.

Program Description- The program uses user defined function: isEqualTo() and evaluates the equality of two entities using function templates.

Explanation of Solution

Program:

/*
Program toevaluate the equality of two entities using function templates. 
.
*/

//header files
#include<iostream>
usingnamespacestd;

//template defined
template<classequalTemplate>

//evaluates equality
boolisEqualTo(equalTemplate input1,equalTemplate input2)
{
//check for qualtiy
if( input1== input2)
returntrue;
elsereturnfalse;
}

//initialize main() function

intmain()
{

int intVal1, intVal2;
double floatVal1, floatVal2;
char charVal1, charVal2;

//Integer Comparison
cout<<"Input two integer values:";
cin>>intVal1>>intVal2;
cout<<intVal1<<" and "<<intVal2<<" are "<<(isEqualTo(intVal1, intVal2)?"Equal":"Not Equal")<<endl;

//Double Comparison
cout<<"Input two floating-point values:";
cin>>floatVal1>>floatVal2;
cout<<floatVal1<<" and "<<floatVal2<<" are "<<(isEqualTo(floatVal1, floatVal2)?"Equal":"Not Equal")<<endl;

//Character Comparison
cout<<"Input two character values:";
cin>>charVal1>>charVal2;
cout<<charVal1<<" and "<<charVal2<<" are "<<(isEqualTo(charVal1, charVal2)?"Equal":"Not Equal")<<endl;

return0;
}

Sample Output-

Input two integer values:23 44

23 and 44 are Not Equal

Input two floating-point values:23.33 45.5

23.33 and 45.5 are Not Equal

Input two character values: a A

a and A are Not Equal
