1001 Sum Problem
Problem Description
Hey, welcome to HDOJ(Hangzhou Dianzi University Online
Judge).
In this problem, your task is to calculate SUM(n) = 1 + 2 + 3
+ ... + n.
Input
The input will consist of a series of integers n, one integer
per line.
Output
For each case, output SUM(n) in one line, followed by a blank
line. You may assume the result will be in the range of 32-bit
signed integer.
Sample Input
1
100
Sample Output
1
5050

解答：
#include
main()
{ int n,i,sum;
sum=0;
while((scanf("%d",&n)!=-1))
{
sum=0;
for(i=0;i<=n;i++)
sum+=i;
printf("%d\n\n",sum);
}
}

(I)
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

(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.

解答：
#include
#define M 1000
void main()
{
int a ,b,n,j[M],i;
//printf("please input n:\n");
scanf("%d",&n);
for(i=0;i
{
scanf("%d%d",&a,&b);
//printf("%d %d",a,b);
j[i]=a+b;
}
i=0;
while(i
{
printf("%d",j[i]); i++;
printf("\n");
}
}
1091A+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.
Sample Input
1 5
10 20
0 0
Sample Output
6
30

}
1092A+B for Input-Output Practice (IV)
Problem Description
Your task is to Calculate the sum of some integers.
Input
Input contains multiple test cases. Each test case contains a
integer N, and then N integers follow
in the same line. A test case starting with 0 terminates the
input and this test case is not to be processed.
Output
For each group of input integers you should output their sum
in one line, and with one line of output for each line in input.
Sample Input
4 1 2 3 4
5 1 2 3 4 5
Sample Output
10
