Problem Name: Arrays Introduction

Problem Link:

In this HackerRank Functions in C++ programming problem solution,

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier.

For arrays of a known size, 10 in this case, use the following declaration:

int arr[10]; //Declares an array named arr of size 10, i.e, you can 
store 10 integers.

Note Unlike C, C++ allows dynamic allocation of arrays at runtime without special calls like malloc(). If n = 10, int arr[n] will create an array with space for 10 integers.

Accessing elements of an array:


Indexing in arrays starts from 0.So the first element is stored at 
arr[0],the second element at arr[1] and so on through arr[9].

You will be given an array of N integers and you have to print the integers in the reverse order.

Input Format

The first line of the input contains N ,where N is the number of integers.The next line contains N space-separated integers.


  • 1 <= N <= 1000
  • 1 <= A[i] <= 10000, where A[i] is the i**th integer in the array.

Output Format

Print the N integers of the array in the reverse order, space-separated on a single line.

Sample Input

1 4 3 2

Sample Output

2 3 4 1

    for(int i = 0; i < N; i++)
        cin >> arr[i];

    for(int i = N - 1; i >= 0; i--)
        cout << arr[i] << " ";
    cout << endl;

    return 0;
