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

- Create a struct called Complex for performing arithmetic with complex numbers. Write a driver program to test your struct. Complex numbers have the form: realPart + imaginaryPart * iwhere i is the square root of -1Use double variables to represent data of the struct. Provide a function that enables an object of this struct to be initialized when it is declared. The function should contain default values in case no initializers are provided. Also provide functions for each of the following:a) Addition of two Complex numbers: The real parts are added together and the imaginary parts are added together.b) Subtraction of two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.c) Printing Complex numbers in the form (a, b) where a is the real part and b is the imaginary partSubmit one file which contains all code above: the structure…

- In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…arrow_forwardConsider the function void modify(int & x) { x = 10; }Show how to call the modify function so that it sets the integer int i;to 10.arrow_forwardWhat must you be sure of when passing a class object to a function template that uses an operator, such as * or >?arrow_forward
- (The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Use the MyDate class defined in Programming Exercise 10.14 – see the textbook - to create an object for date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person's name.
