2、aratedbyaspace,onepairofintegersperline.输出Foreachpairofinputintegersaandbyoushouldoutputthesumofaandbinoneline,andwithonelineofoutputforeachlineininput.样例输入151020样例输出630提示这是一个求两数之和的题目，输入多对用空格分开的两个数ab，输出a+b的和，每一对数据的和占一行。编写代码时需要注意的是，由于没有指出有多少对输入数据，因此我们可以编写如下代码：//C语言#includeintmai

3、n()//把main函数定义成int类型{inta,b;while(scanf("%d%d",&a,&b)!=EOF)//输入结束时，scanf函数返回值为EOF，即没有数据输入时则退出while循环printf("%d",a+b);return0;//返回值为0}//或者C++语言#include//注意头文件的使用方法usingnamespacestd;intmain(){inta,b;while(cin>>a>>b)cout<
