C++ Program Add Two Numbers using Class and Function

Source Code: 

#include <iostream>
using namespace std;
class Add{
  public:
    /* Two variables that we are going to
     * add. If you want to add float or double
     * variables instead, just change the data
     * type. for example: float num1, num2;
     */
    int num1, num2;

    /* This function ask the user for two numbers.
     * The numbers that user enter are stored into
     * num1 and num2 variables so that we can add
     * them later.
     */
    void ask(){
       cout<<"Enter first number: ";
       cin>>num1;
       cout<<"Enter second number: ";
       cin>>num2;
    }

    /* This function adds the numbers that are passed
     * to it through arguments. I have used parameter names
     * as n1 and n2 but you can choose any parameter name.
     * This function returns the result.
     */
    int sum(int n1, int n2){
       return n1+n2;
    }

    //This function displays the addition result
    void show(){
       cout<<sum(num1, num2);
    }
};
int main(){
   //Creating object of class Add
   Add obj;

   //asking for input
   obj.ask();

   //Displaying the output
   obj.show();
   return 0;
}
