Problem Description
Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.
Input
The input will consist of a series of pairs 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
1 5
10 20
Sample Output
6
30
/*#include<stdio.h>
int main()
{
int a,b;
while(scanf("%d%d",&a,&b)!=EOF)
{
printf("%d ",a+b);
}
return 0;
}
//第一种 没有说明几组数据的，要以 EOF 结束。 hdu 1089*/

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

*#include<stdio.h>
int main()
{
int a,b,n;
scanf("%d",&n);
while(n--)
{
scanf("%d%d",&a,&b);
printf("%d ",a+b);
}
return 0;
} //第二种，输入一个整数，用一个循环（while或其他）来控制。 不要忘记加换行 “ ” hdu 1090

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.
Sample Input
1 5
10 20
0 0
Sample Output

#include<stdio.h>
int main()
{
int a,b;
while(scanf("%d%d",&a,&b)&&(a!=0||b!=0))
{
printf("%d ",a+b);
}
return 0;
}
// 第三种，遇到输入a,b都为0的结束。注意输入是 判断 a b 是否为0 或’||‘和 ”&&“之间的区别。Hdu1091
