mycode.cpp

#include <iostream>
#include "my_add.h"
#include "my_sub.h"
#include "my_div.h"
using namespace std;

// Function prototype (declaration)
int my_add(int, int);
int my_sub(int, int);
int my_div(int, int);
int main()
{
int x, y, sum,sub,div;
cout<<"Enters two numbers: ";
cin >> x >> y;

// Function call
sum = my_add(x, y);
cout << "Sum = " << sum <<endl;
  
sub = my_sub(x,y);
   cout << "Sub = " << sub<<endl;
  
   div = my_div(x,y);
   cout << "Div = " << div<<endl;
  
   return 0;
}
