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

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 
int main()
{
	int a,b;
	while(scanf("%d%d",&a,&b)!=EOF)
	{
		if(a==0 && b==0)
			break;
		printf("%d\n",a+b);
	}
	return 0;
}
