Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    for(int i=0;i<=n-k;i++){
int sum=0;

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

}
    }
}

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;
}
