Getting Started with C# Programming
Objective
The objective of this exercise is to develop a C# program that prompts the user for a number and prints a 3x5 rectangle using that digit, demonstrating how to manipulate text-based output.
Write a C# program to prompt the user for a number and then display a rectangle 3 columns wide and 5 rows high using that digit.
Example C# Exercise
Show C# Code
// First and Last Name: John Doe
using System;
namespace RectanglePattern
{
class Program
{
// The Main method is where the program execution begins
static void Main(string[] args)
{
// Declare a variable to store the user's digit
char digit;
// Prompt the user to enter a single digit
Console.Write("Enter a digit: ");
digit = Console.ReadKey().KeyChar; // Read a single character from user input
Console.WriteLine("\n"); // Move to the next line
// Print the first row (solid row)
Console.WriteLine("{0}{0}{0}", digit);
// Print the middle three rows (hollow part)
Console.WriteLine("{0} {0}", digit);
Console.WriteLine("{0} {0}", digit);
Console.WriteLine("{0} {0}", digit);
// Print the last row (solid row)
Console.WriteLine("{0}{0}{0}", digit);
// Wait for user input before closing the program
Console.ReadKey(); // Keeps the console open until a key is pressed
}
}
}
Output
//Example 1:
Enter a digit: 3
333
3 3
3 3
3 3
333
//Example 2:
Enter a digit: 8
