Proposed exercise
Write a C# program to ask the user for his/her name and a size, and display a hollow rectangle with it:
Enter your name: Yo
Enter size: 4
YoYoYoYo
Yo____Yo
Yo____Yo
YoYoYoYo
(note: the underscores _ should not be displayed on screen; you program should display blank spaces inside the rectangle)
Solution
using System;
public class Rectangle
{
public static void Main()
{
int n, width, height;
int row,column;
Console.Write("Enter a number: ");
n = Convert.ToInt32( Console.ReadLine() );
Console.Write("Enter the desired width: ");
width = Convert.ToInt32( Console.ReadLine() );
Console.Write("Enter the desired height: ");
height = Convert.ToInt32( Console.ReadLine() );
for (row = 0; row < height; row++)
{
for (column = 0; column < width; column++)
Console.Write(n);
Console.WriteLine();
}
}
}
