Description

The reverse of array means the elements we entered first will come last.
example:
if we have array, arr[] = {1,2,3}
then reverse of array will be {3,2,1}
  
To reverse the array, we start traversing the array from end to start 
and print the corresponding elements.

C/C++

/*C program to print reverse of the array*/
//Save it as ReverseArray.c

#include<stdio.h>
int main(){

    int i,n;

    printf("Enter the size of array : ");
    scanf("%d",&n);

    int arr[n];

    printf("Enter the array elements : ");
    for(i=0;i<n;i++) {
        scanf("%d",&arr[i]);
    }

    printf("The Entered elements are : ");
    for(i=0;i<n;i++) {
        printf("%d ",arr[i]);
    }

    printf("\nThe reverse of array is : ");
    for(i=n-1;i >= 0;i--) {
        printf("%d ",arr[i]);
    }
    return 0;
}

Input:
Enter the size of array : 
5
Enter the array elements : 
2
3
5
6
1
Output:
The Entered elements are : 
2 3 5 6 1 
The reverse of array is : 
1 6 5 3 2

Java

/*Java program to print reverse of the array*/
//Save it as ReverseArray.java

public class ReverseArray {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        
        System.out.println("Enter the size of array : ");
        int n = scanner.nextInt();
        
        
        //Declaring the array
        
        int arr[] = new int[n];
        
        System.out.println("Enter the array elements : ");

        for(int i=0;i<n;i++) {
            arr[i] = scanner.nextInt();
        }
        
        System.out.println("The Entered elements are : ");
        for(int i=0;i<n;i++) {
            System.out.print(arr[i] + " ");
        }
        System.out.println();
        
        System.out.println("The reverse of array is : ");
        for(int i=n-1;i >= 0;i--) {
            System.out.print(arr[i] + " ");
        }
    }
}
