Input data must be read from console and the result must be written to console as well. The main function should return zero.

Example. Create a program which calculates the sum of two integer numbers.

Sample input:
5 3

Sample output:
8

Sample code:

#include <iostream>

using namespace std;



int main()

{

   int a,b;

   cin>>a>>b;

   cout<<a+b;

   return 0;

}
