Develop a C program to find the sum of array elements using user-defined function. (Note: pass array as an argument in function)

Code

#include <stdio.h>

// function to calculate the sum of array
// elements
int sum_of_elements(int *arr, int n)
{
    int i = 0, sum = 0;

    for (i = 0; i < n; i++)
    {
        sum = sum + arr[i];
    }

    return sum;
}

// main function
int main()
{
    int n, i, res;

    printf("Enter number of elements: ");
    scanf("%d", &n);

    int array[n];

    for (i = 0; i < n; ++i)
    {
        printf("Enter number%d: ", i + 1);
        scanf("%d", &array[i]);
    }

    // Passing array to Function
    res = sum_of_elements(array, n);

    printf("\nThe sum of all array elements is : %d\n", res);

    return 0;
}
