Problem Statement

Write a C program to compute the sum of all elements in a 1D array.

Input Format

The first line contains N (size of array). The second line contains N space-separated integers.

Output Format

Print the total sum of array elements.

Constraints

1 <= N <= 1000, -10000 <= Elements <= 10000

Sample Input

5
1 2 3 4 5

Sample Output

15

Explanation

Sum = 1 + 2 + 3 + 4 + 5 = 15.

Starter Code

#include <stdio.h>

int main() {

        int arr[n];
        for (int i = 0; i < n; i++) {
            scanf("%d", &arr[i]);
        }
        // Write your code here
    }
    return 0;

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
