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

this project is NOT for graded(marks) purposes, please help me with the introduction. give me answers for the project. i will include an image explaining everything about the project.
Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
