Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int temp = 0x00;
    if(k > n)
    {
        return;
    }
    else
    {
        for(int i = 0; i < k; i++)
        {
            temp = temp + arr[i];
        }
        printf("%d ",temp);

        for(int i = k; i < n;i++)
        {
            temp = temp - arr[i - k] + arr[i];
            printf("%d ",temp);
        }

    }
}

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;
}
