[align=left]Output[/align]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.

<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);
  }
}
