Calculate a + b
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
Sample Output
6
Hint
Use + operator
scanf函数返回成功读入的数据,读入数据时遇到了“文件结束”则返回EOF。
#include<iostream>
using namespace std;
int main()
int a, b, c;
while(scanf("%d %d", &a, &b)!=EOF)
printf("%d\\n", a + b);
return 0;
