Proposed exercise
Write a program which asks for a symbol, a width and a height and displays a hollow rectangle of that width and that height, using that number for the outer symbol, as in this example:
Enter a symbol: 4
Enter the desired width: 3
Enter the desired height: 5
444
4 4
4 4
4 4
444
Output
Solution
using System;
public class HollowRectangle
{
public static void Main()
{
int row, column;
Console.Write("Enter a symbol: ");
int symbol = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter the width: ");
int width = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter the 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();
}
}
