CSU 1000/1001/1002 A+B问题
1000：
Description
Your task is to Calculate a + b.
Input
Input contains multiple test cases. Each test case consists of a pair of integers a and b（0<=a,b<=20）, 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 1
Sample Output
2
代码：
-
#include<iostream>
-
using namespace std;
-
-
int main()
-
{
-
inta, b;
-
while(cin >> a >> b)
-
{
-
cout << a + b << endl;
-
}
-
return 0;
-
}

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 real number a and b（0<=a,b<=1000000）, separated by a space.
Output
For each case, output the answer in one line rounded to 4 digits after the decimal point.
Sample Input

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 <=1016）, 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.
