Program to find the sum of all array elements using function in C

/*  
* C program to a pass integer array elements to 
* a function and return the sum of all elements
*/

#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 total = 0;
    int array[10] = {1,2,3,4,5,6,7,8,9};
    
    // Passing array to Function
    total = sum_of_elements(array,9);
	
    printf("\nThe sum of all array elements is : %d",total);
	
    return 0;
}

Output

The sum of all array elements is : 45
