A program for finding the results of a+b and a-b.

Time Limit: 1000/2000 MS (C/Others)   Memory Limit: 65536/512 K (C/Others)

Input:

There are multiple sets of data, each time entering two numbers, a and b, separated by spaces, one pair of integers per line. (|a|,|b|<=2^62), |a|, |b| denote the absolute value of a, b.

Output:

For each pair of integers a and b, you should output the answers for a+b and a-b on one line, separated by spaces.

Sample Input:

1 2

3 3

Sample Output:

3 -1

Source code：

#include<stdio.h>

#include<math.h>

int main(void){

int a, b, result1, result2;

        while(scanf("%d %d", &a, &b)!=EOF){

result1 = a + b;

result2 = a - b;

if(fabs(a) < 2^62 & fabs(b) < 2^62){

printf("%d %d", result1, result2);

}

}

return 0;
