#include<conio.h>

classcalc

{

public:

voidsetdata()

{

cout<<"Enter the value of a:";

cin>>a;

cout<<"Enter the value of b:";

cin>>b;

}

int addition()

{

returna+b;

}

int subtraction()

{

return a-b;

}

int multiplication()

{

return a*b;

}

int division()

{

return a/b;

}

};

int main()

{

calc c;

intch;

int r;

clrscr();

c.setdata();

do

{

cout<<"Enter 1 for Addition"<<endl;

cout<<"Enter 2 for Subtraction"<<endl;

cout<<"Enter 3 for Multiplication"<<endl;

cout<<"Enter 4 for Division"<<endl;

cout<<"Enter 5 for Exit"<<endl;

cin>>ch;

switch(ch)

{

case 1:

cout<<"Addition="<<c.addition();

break;

case 2:

cout<<"Subtraction="<<c.subtraction();

break;

case 3:

cout<<"Multiplication="<<c.multiplication();

break;

case 4:

cout<<"Division="<<c.division();

break;

case 5:

exit();

}

}while(ch!=5);

}
