```

### Input

```c

#include 

int main() {

    int arr[3] = {10, 20, 30}; // Example array of 3 integers

    int sum = 0;

    

    // Loop through the array and calculate the sum

    for (int i = 0; i <= 2; i++) {

        sum += arr[i];

    }

    

    // Output the sum

    printf("The sum of the array elements is: %d\n", sum);

    

    return 0;

}

```
