C program to reverse an array

Below is the code to reverse the elements in an array

#include <stdio.h>
int main(){
    int i,j,n;
    printf("Enter size of an array:");
    scanf("%d",&n);
    int arr[n];
    printf("Enter elements in an array:");
    for(i=0;i<n;i++){
        scanf("%d",&arr[i]);
    }
    int temp;
    for(i=0;i<n/2;i++){
        temp=arr[i];
        arr[i]=arr[n-i-1];
        arr[n-i-1]=temp;
    }
    printf("Elements in the array after reversing:");
    for(i=0;i<n;i++){
        printf("%d\n",arr[i]);
    }
}

Output:

Enter size of an array:5
Enter elements in an array:4
7
8
2
9
Elements in the array after reversing:9
2
8
7
4
