Reverse an Array In-Place

Code

#include <stdio.h>


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

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }
   int arr1[n];
    for(int i=0;i<n;i++)
    {
        arr1[i]=arr[n-i-1];

        
    }
    

    for (int i = 0; i < n; i++) {
        printf("%d", arr1[i]);
        if(i < n-1){
        	printf(" ");
        }
    }
    return 0;
}
