武汉科技大学ACM ：1002: A+B for Input-Output Practice (II)-布布扣-bubuko.com

Problem Description

Your task is to Calculate a + b.

Input

Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair 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

2
1 5
10 20

Sample Output

6
30

 1 #include<iostream>
 2 #include<string>
 3 using namespace std;
 4 int main()
 5 {
 6     int n,a,b;
 7     int sum;
 8     string result;
 9     char s[100];
10     cin>>n;
11     for(int i=0;i<n;i++)
12     {
13         cin>>a;
14         cin>>b;
15         sum = a+b;
16         sprintf(s, "%d",sum);//将整数转为字符串型
17         result += s;
18         result += "\n";
19     }
20     cout<<result;
21     return 1;
22 }
