Question
Chapter 23, Problem 23.3E
Program Plan Intro
- 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.
Expert Solution & Answer
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

Please pay attention to the required data types in the description. Thetuple, list and vector classes and their objects are not allowed to be used.
1. Define a new C++ class named “PayStub” that manages pay information: number of hours (integer), hourly pay rate (double). The total payout amount will be calculated based on overtime. Any hour that ismore than 40 hours will be paid at 1.5 pay rate.
For example, with the hourly pay rate of $10.0 and if the number of hours is 40, the payout amount will be 400 and if the number of hours is 50 it will be (40 * 10)+ (10 * 15) = 550Please note that because the payout is a calculated value, it should not be part of the data members to make the object as small as possible.
The class must provide at least the following two methods:• toString method that returns the string containing all the information about the paystub including the total payout amount.
For example, here is the output for different paystubs:40 hours at $10.0 an hourHOURS(40)…
