Write a C# program to ask the user for a number and display ir four times in a row, separated with blank spaces, and then four times in the next row, with no separation. You must do it two times: first using Console.Write and then using {0}.

Code:

using System;
public class exercise12
{
    public static void Main()
    {
        int n;
        Console.WriteLine("Enter a digit: ");
        n = Convert.ToInt32(Console.ReadLine());

        // Part A: "n n n n" using Write
        Console.Write(n);
        Console.Write(" ");
        Console.Write(n);
        Console.Write(" ");
        Console.Write(n);
        Console.Write(" ");
        Console.Write(n);
        Console.WriteLine();

        // Part B: "nnnn" using Write
        Console.Write(n);
        Console.Write(n);
        Console.Write(n);
        Console.WriteLine(n);
        Console.WriteLine();

        // Part C: "n n n n" using {0}
        Console.WriteLine("{0} {0} {0} {0}", n);

        // Part D: "nnnn" using {0}
        Console.WriteLine("{0}{0}{0}{0}", n);
    }
}
