Sliding Window Sum

Code

#include <stdio.h>

int getWindowSum(int arr[], int idx ,int  k){
    int temp = 0;
    for(int i = idx; i <(k + idx );  i++){
        temp += arr[i];
    }
    return temp;
}

void sliding_window_sum(int arr[], int n, int k) {
    for(int i = 0; i< n-k+1; i++){
        printf("%d ", getWindowSum(arr, i, k));
    }
}

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;
}
