Solution
using System;
public class HollowSquare
{
    public static void Main()
    {
        int row, column;
        
        Console.Write("Enter a symbol: ");
        int symbol = Convert.ToInt32(Console.ReadLine());
        
        Console.Write("Enter the desired width: ");
        int width = Convert.ToInt32(Console.ReadLine());
        
        Console.Write("Enter the desired height: ");
        int height = Convert.ToInt32(Console.ReadLine());
        
        Console.WriteLine(); 
        
        for(row = 1; row <= height; row++)
        {
            for(column = 1; column <= width; column++)
            {
                if ((row == 1) || (row == height))
                    Console.Write(symbol);
                else
                {
                    if ((column == 1) || (column == width))
                        Console.Write(symbol);
                    else
                        Console.Write(" ");
                }
            } 
            Console.WriteLine();                 
        }
