HDU 1.1.3 A+B for Input-Output Practice (III)

 

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

1 510 200 0

 

Sample Output

630

 

#include <stdio.h>int main(void){int a, b;scanf("%d%d", &a, &b);while(a != 0 || b != 0)               {printf("%d\n", a + b);scanf("%d%d", &a, &b);}return 0;}
