In this article, we will learn how to find the sum of elements of an array using a C program.

The simplest method to calculate the sum of elements in an array is by iterating through the entire array using a loop while adding each element to the accumulated sum.

C

#include <stdio.h>  int getSum(int arr[], int n) {      // Initialize sum to 0     int sum = 0;     for (int i = 0; i < n; i++) {          // Add each element to sum         sum += arr[i];     }     return sum; }  int main() {     int arr[] = {1, 2, 3, 4, 5};     int n = sizeof(arr) / sizeof(arr[0]);    	// Find the sum     int res = getSum(arr, n);        printf("%d", res);     return 0; }

Output

The above method can also be implemented using recursion.

Using Recursion

In this method, each recursive call adds the current element to the sum and then moves on to calculate the sum of the remaining array until there are no elements left.

C

#include <stdio.h>  int getSum(int arr[], int n) {        // Base case: No elements left     if (n == 0) return 0;          // Add current element and move to the   	// rest of the array     return arr[n - 1] + getSum(arr, n - 1);   }  int main() {     int arr[] = {1, 2, 3, 4, 5};     int n = sizeof(arr) / sizeof(arr[0]);          // Finding the sum     int res = getSum(arr, n);      printf("%d", res);     return 0; }
