問題簡(jiǎn)述：實(shí)現(xiàn)簡(jiǎn)單的加法運(yùn)算，對(duì)輸入的A痊班，B值進(jìn)行加法計(jì)算并輸出結(jié)果
程序分析：由于題目要求對(duì)多行數(shù)據(jù)進(jìn)行計(jì)算摹量，所以循環(huán)體的條件為cin>>a>>b馒胆；即當(dāng)輸入Ctrl+z時(shí)停止程序祝迂；
AC的C++代碼如下
#include<iostream>
using namespace std;
int main()
{
int a,b;
while (cin >> a >> b)
{
cout<< a + b << endl;
}
return 0;
}
