Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int tg=0, tg1 = 0;
    int number_of_win = n-k+1;
    for(int i=0; i<number_of_win; i++){
        for(int j=0; j<k; j++){
            tg = arr[i+j];
            tg1 += tg;
            tg = 0;
        }
        arr[i] = tg1;
        printf("%d ", arr[i]);
        tg1 = 0;
    }
}

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;
}
