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

 

代码：

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