Problem Description
Your task is to Calculate a + b.

Input
Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.

Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

Sample Input
1 5
10 20
0 0

Sample Output
6
30

#include <stdio.h>
int main()
{int a,b;
 while(scanf("%d %d",&a,&b),a||b)
 {printf("%d\n",a+b);
        }
