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 5 10 20 0 0

Sample Output 6 30

<code>

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