By chandan singh - Saturday, 9 September 2017 -

Given an array of

integers, can you find the sum of its elements?

Input Format

The first line contains an integer,

, denoting the size of the array.
The second line contains

space-separated integers representing the array's elements.

Output Format

Print the sum of the array's elements as a single integer.

Sample Input

6
1 2 3 4 10 11

Sample Output

Explanation

We print the sum of the array's elements, which is:

#include <math.h>

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <assert.h>

#include <limits.h>

#include <stdbool.h>

int simpleArraySum(int n, int ar_size, int* ar) {

int i,result = 0;

for (i = 0; i < n; i++)

result = result + ar[i];

return result;

}

int main() {

int n;

scanf("%i", &n);

int *ar = malloc(sizeof(int) * n);

for(int ar_i = 0; ar_i < n; ar_i++){

scanf("%i",&ar[ar_i]);

}

int result = simpleArraySum(n, n, ar);

printf("%d\n", result);

return 0;

}
