Explanation:

#include <iostream>

using namespace std;

//class definition

class Numbers

{

private:

int a;

int b;

public:

//member function declaration

void readNumbers(void);

void printNumbers(void);

int calAddition(void);

};

//member function definitions

void Numbers::readNumbers(void)

{

cout<<"Enter first number: ";

cin>>a;

cout<<"Enter second number: ";

cin>>b;

}

void Numbers::printNumbers(void)

{

cout<<"a= "<<a<<",b= "<<b<<endl;

}

int Numbers::calAddition(void)

{

return (a+b);

}

//main function

int main()

{

//declaring object

Numbers num;

int add; //variable to store addition

//take input

num.readNumbers();

//find addition

add=num.calAddition();

//print numbers

num.printNumbers();

//print addition

cout<<"Addition/sum= "<<add<<endl;

return 0;
