Question

Write a program that consists of a main function and a class called Number.  

The Number class should allow a class instance to add to itself the member-variable values of another class instance.

For example, let x and y both be instances of the Number class.  

Then x.Add(y) will have the affect such that whatever value y holds, that value will then be added to x.

Implement Add, Subtract, and Multiply.  The member-variables x and y shall hold integer values.  In the main function, you should design and implement the necessary code to exercise the Number class member function thoroughly.

Explanation / Answer

#include<iostream>

using namespace std;

class Number

{

public:

int a;

Number(int f)

{

a=f;

}

void Add(Number I);

void Sub(Number I);

void Mul(Number I);

void Div(Number I);

};

void Number::Add(Number I)

{

int sum;

sum=a+I.a;

cout<<sum<<" ";

}

void Number::Sub(Number I)

{

int sub;

sub=a-I.a;

cout<<sub<<" ";

}

void Number::Mul(Number I)

{

int mul;

mul=a*I.a;

cout<<mul<<" ";

}

void Number::Div(Number I)

{

float div;

div=(float)a/I.a;

cout<<div;

}

int main()

{

Number x(5);

Number y(10);

x.Add(y);

x.Sub(y);

x.Mul(y);

x.Div(y);

return 0;

}
