A+B for Input-Output Practice (III)
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 <bits/stdc++.h>
using namespace std;
int main()
{
int a,b;
while(~scanf("%d %d",&a,&b)&&(a||b))
{
printf("%d\n",a+b);
}
return 0;
