Sliding Window Sum

Code

#include <stdio.h>

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

    }
}

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;
}
