Sliding Window Sum

Code

#include <stdio.h>
#include <string.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int start, end = 0;
    int windoMax = 0;

    for(end = 0; end < k ; end++){
        windoMax += arr[end];
    }
    printf("%d", windoMax);
    for(end = k; end < n; end++){
        windoMax = windoMax - arr[start] + arr[end];
        printf(" %d", windoMax);
        ++start;
    }
}

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;
}
