acm 1089题
Problem Description
Your task is to Calculate a + b.
Too easy?Of course!I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one,yes,all these problems were designed for the same aim.
Input
The input will consist of a series of pairs of integers a and b,separated by a space,one pair of integers per line.
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
Sample Output
6
30

这种多组输入我纠结了很长时间.
系统说这个程序超过了时间限制
#include
int main()
{
int a,b;
while(1)
{
scanf("%d %d",&a,&b);
if(a==0&&b==0)break;
printf("%d\n",a+b);
}
return 0;
}
我要的是能在acm中提交的,请各位大虾还给点关于做acm的建议.我刚开始做这个的

程序输入不是以0 0结束的,参考程序
#include
int main()
{
int a,b;
while(scanf("%d%d",&a,&b)!=EOF)
{
printf("%d\n", a+b);
}
return 0;
}
