简单的a+b （C语言代码）

#include <stdio.h>

int main(void)

{

        int a=0,b=0;

        while (scanf("%d%d",&a,&b)==2)  //判断是否输入

        {

                if ((a<=1024)&&(b<=1024))  //规定范围,2^10

                        printf("sum:%d\n",a+b);

                else

                {

                        printf("错误 退出!\n");

                        break;

                }

        }

        return (0);

}
