每一个输出模块后有空行，you should output the sum of a and b, and followed by a blank line.
while(scanf("%d %d",&a, &b) != EOF) printf("%d\n\n",a+b);
输出结果之间有空行 you must note that there is a blank line between outputs.
if(T+1)
printf("%d\n\n",sum);
else
printf("%d\n",sum);


if(i<icase)
printf("%d\n\n",sum);
else
printf("%d\n",sum);
