Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    int i,j=0,s=0,b[n],o=0;
    for(i=0;i<n-k+1;){
        int t=i;
        while(j<k){
            s=s+arr[i];
            j++;
            i++;
        }
        printf("%d ",s);
      i=t;j=0;s=0;i++;o++;

        }
        
        }

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;
}
