武汉科技大学ACM ：1002: A+B for Input-Output Practice (II)
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
21 510 20
Sample Output
630
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 }
