Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int curr_sum=0;
    for(int i =0 ; i < k ; ++i)
    {
        curr_sum += arr[i];
        
    }
    printf("%d ",curr_sum);
    for (int i = k ; i < n ; ++i)
    {
        curr_sum = curr_sum - arr[i - k] + arr[i];
        printf("%d ",curr_sum);
    }
    

}

int main() {
    int n, k, arr[100];
    scanf("%d %d", &n, &k);
    for (int i = 0; i < n; i++) scanf("%d", &arr[i]);

    sliding_window_sum(arr, n, k);
    return 0;
}
