SZTUOJ 1003.A+B(III)

Description

Your task is to Calculate a + b.

Input

There are multiple test cases. Each test case contains only one line. Each line consists of a pair of integers a and b ( 1 <= a, b <=10e16 ) , separated by a space. Input is followed by a single line with a = 0, b = 0, which should not be processed.

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
10000000000000000 10000000000000000
0 0

Sample Output

6
30
20000000000000000

题目解析

这道题其实和前两个题目没有什么本质上的区别，只是题目要求遇到a和b都等于0的时候退出循环，所以我们不在对比EOF，而是在循环中直接加一个判断条件决定是否结束读入，然后注意题目的数据范围超过了int类型，需要用long long int来存储，除此以外没有其他的更多坑点了。

代码实现

#include<bits/stdc++.h>
using namespace std;
int main()
{
long long int a,b;
while(cin>>a>>b)
{
if(a==0&&b==0)break;
a=a+b;
printf("%lld\n",a);
}
return 0;
}
