A+B for Input-Output Practice (III)

Problem Description

---

Your task is to Calculate a + b.

---

Input
Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to 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.

Example Input

---

1 510 200 0

---

Example Output

---

630

代码：

#include <stdio.h>#include <stdlib.h>int main(){    int sum, a, b;    while(scanf("%d %d", &a, &b) != EOF && (a || b))    {        sum = a + b;        printf("%d\n", sum);    }    return 0;}
