It's dangerous to code alone! Take this.

The Replicator of D'To

The following is one possible solution to this challenge.

using System;

int[] original = new int[5];

for(int item = 0; item < 5; item++)
{
    Console.Write("Enter a number: ");
    int number = Convert.ToInt32(Console.ReadLine());
    original[item] = number;
}

int[] copy = new int[5];

for (int index = 0; index < 5; index++)
    copy[index] = original[index];

for (int index = 0; index < 5; index++)
    Console.WriteLine($"{original[index]} and {copy[index]}");
