C# Alphabet Pattern 19

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 <= 4; j++) {
          if (j <= i)
            Console.Write(alpha[j]);
          else
            Console.Write(" ");
        }
        for (k = 4; k >= 0; k--) {
          if (k > i)
            Console.Write(" ");
          else
            Console.Write(alpha[k]);
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

A        A
AB      BA
ABC    CBA
ABCD  DCBA
ABCDEEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; statement, which allows the usage of various types and methods from the System namespace.
The program defines a new namespace called myApp using the namespace keyword. A namespace is a way to organize code and prevent naming conflicts.
Inside the myApp namespace, the program defines a class called Program using the class keyword. Classes are the fundamental building blocks of C# programs and encapsulate data and behavior.
Within the Program class, there is a static void Main(string[] args) method. This is the entry point of the program, where the execution begins.
Inside the Main method, three integer variables are declared: i, j, and k. These variables will be used as loop counters.
A character array called alpha is initialized with the English uppercase alphabet using the ToCharArray method. This array will be used to print letters in the pattern.
The program enters a nested loop structure using two for loops. The outer loop runs from i=0 to i<=4, and the inner loop runs from j=0 to j<=4.
Within the inner loop, there is an if-else statement. If j is less than or equal to i, it prints the j-th letter from the alpha array using Console.Write(alpha[j]). Otherwise, it prints a space character.
After the inner loop finishes, the program enters another loop using for(k=4; k>=0; k--). This loop is responsible for printing the right side of the pattern.
Within this loop, there is another if-else statement. If k is greater than i, it prints a space character. Otherwise, it prints the k-th letter from the alpha array in reverse order using Console.Write(alpha[k]).
Once the second loop is complete, the program moves to a new line using Console.WriteLine() to start the next line of the pattern.
The outer loop continues to iterate until i reaches 4, completing the pattern.

💯 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.
