C# Alphabet Pattern 18

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

example.cs

Copied

using System;

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

💻 Testing the Program

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

Output

A
ABA
ABCBA
ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The using System; statement includes the System namespace, which allows the program to access standard types and members such as input/output (IO) functionalities.
The program declares a namespace myApp. Namespaces are used to organize code and prevent naming conflicts.
Inside the myApp namespace, there's a class Program, which contains the Main method. The Main method is the entry point of the program and will be executed when the program starts.
Three integer variables i, j, and k are declared to be used in the loops.
The program creates a character array alpha containing all uppercase English letters by converting the string "ABCDEFGHIJKLMNOPQRSTUVWXYZ" to a character array using ToCharArray().
The program starts a loop with i ranging from 0 to 4 (inclusive). This loop controls the rows of the pattern to be printed.
Inside the outer loop, there are two nested loops:
1. The first nested loop (with j) runs from 0 to the current value of i (inclusive). This loop prints the first part of the pattern, where the letters are in increasing order.
2. The second nested loop (with k) runs from i-1 to 0 (inclusive). This loop prints the second part of the pattern, where the letters are in decreasing order. Note: i-1 is used because we want to avoid printing the letter at the center of the pattern twice.
After both nested loops finish, the program writes a new line using Console.WriteLine(), which moves the cursor to the next line for the next row of the pattern.
The outer loop repeats until i reaches 4, and the entire pattern is printed.

💯 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.
