HDU 1.1.6 A+B for Input-Output Practice (VI)

Problem Description Your task is to calculate the sum of some integers.

Input Input contains multiple test cases, and one case one line. Each case starts with an integer N, and then N integers follow in the same line.

Output For each test case you should output the sum of N integers 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 15

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