Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) 
{
    int *start = arr;
    int *end = arr + n -1;

    while(start<end)
    {
        int tmp = *(start);
        *start = *(end);
        *end = tmp;

        start++;
        end--;

    }

    // Your logic here
}

int main() {
    int n;
    scanf("%d", &n);

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if(i < n-1){
        	printf(" ");
        }
    }
    return 0;
}
