C++ program to add two numbers

C++ program to add two numbers.

C++ programming code

#include <iostream>
 
using namespace std;
 
int main()
{
   int a, b, c;
 
   cout << "Enter two numbers to add\n";
   cin >> a >> b;
 
   c = a + b;
   cout <<"Sum of entered numbers = " << c << endl;
 
   return 0;
}

C++ addition program using class

#include <iostream>
 
using namespace std;
 
class Mathematics {
  int x, y;
 
public:
  void input() {
    cout << "Input two inetegers\n";
    cin >> x >> y;
  }
 
  void add() {
    cout << "Result = " << x + y;
  }
 
};
 
int main()
{
   Mathematics m; // Creating object of class
 
   m.input();
   m.add();
 
   return 0;
}

We create Mathematics class with two functions input() and add(). First function is used to get two integers and add() performs addition and display the result. Similarly you can add more functions such as subtract, multiply, divide etc.
