C# Alphabet Pattern 28

Here`s a program that prints the above alphabet pattern using C# Programming:

example.cs
Copied
Copy To Clipboard
using System;

namespace myApp {
  class Program {
    static void Main(string[] args) {
      int i, j;
      int k = 4;
      char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();
      for (i = k; i >= 0; i--) {
        for (j = k; j >= 0; j--) {
          if (j > i)
            Console.Write("{0} ", alpha[j]);
          else
            Console.Write("{0} ", alpha[i]);
        }
        for (j = 1; j <= k; j++) {
          if (j > i)
            Console.Write("{0} ", alpha[j]);
          else
            Console.Write("{0} ", alpha[i]);
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output
E E E E E E E E E
E D D D D D D D E
E D C C C C C D E
E D C B B B C D E
E D C B A B C D E

🧠 How the Program Works

Let's break down the logic behind the code:

  1. The program begins by including the necessary namespace System, which provides access to fundamental classes and base types (such as Console) in the C# language.
  2. The program defines a new namespace myApp. Namespaces are used to organize code and prevent naming conflicts.
  3. Inside the myApp namespace, there's a class called Program.
  4. The Main method is the entry point of the program. It is declared as static, meaning it belongs to the class itself rather than an instance of the class.
  5. The Main method takes a string[] argument named args. This is an array of strings that can be passed as command-line arguments when running the program.
  6. The Main method defines three variables: i, j, and k. i and j are of type int, while k is initialized with the value 4.
  7. A char array named alpha is defined and initialized with the characters of the English alphabet in uppercase ("ABCDEFGHIJKLMNOPQRSTUVWXYZ"). The ToCharArray() method converts the string into an array of characters.
  8. The program enters a nested loop with a for loop. The outer loop iterates from k down to 0, and the loop variable is i.
  9. Inside the outer loop, there are two inner for loops.
  10. The first inner loop also iterates from k down to 0, and the loop variable is j.
  11. For each combination of i and j, the program checks if j is greater than i. If j is greater, it prints the character at index j from the alpha array. Otherwise, it prints the character at index i from the alpha array.
  12. After printing the characters in the first half of the line, the second inner for loop is used to print the characters in the second half of the line.
  13. This loop iterates from 1 to k, and again, the program checks if j is greater than i to determine which character to print.
  14. After completing both inner for loops, the program prints a new line using Console.WriteLine() to move to the next line for the next iteration of the outer loop.
  15. The outer loop continues to iterate until i becomes 0, and the program prints the desired pattern based on the conditions specified in the if-else statements.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.

✔ Conclusion:

Creating visually appealing patterns is not only a fun endeavour but also a great way to enhance your programming or design skills. We hope this tutorial has inspired you to explore the world of creative coding. Share your creations with us, and let your imagination run wild!
