Simple Array Sum in C programming Language

Question:

Given an array of integers, 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

Solution:

#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) {
    // Complete this function
    int sum=0;
    int i;
    for(i=0;i<n;i++){
        sum=sum+ar[i];
    }
    return sum;
}
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;
}
