Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int l = 0; 
    int r = k;
    int sum = 0;
    int arr_print[100];
    int ite = 0;

    for (int i = 0; i < k; i++)
    {
        sum += arr[i]; 
    }

    arr_print[ite++] = sum; 

    while (r < n)
    {
        sum -= arr[l]; 
        sum += arr[r]; 
        l++; 
        r++; 
        arr_print[ite++] = sum;
    }

    for (int i = 0; i < ite; i++)
    {
        printf("%d ", arr_print[i]);
    }

}

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;
}
