Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) 
{
    int j, temp;

    for(j=0; j<n/2; j++)  
    {
        temp = arr[j];
        arr[j] = arr[n-j-1];
        arr[n-j-1] = temp;
    }  
}

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;
}
