C# Alphabet Pattern 31

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 (i == j)
            Console.Write(alpha[j]);
          else
            Console.Write(" ");
        }
        for (k = 3; k >= 0; k--) {
          if (i == k)
            Console.Write(alpha[k]);
          else
            Console.Write(" ");
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

A       A
 B     B
  C   C
   D D
    E

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; statement, which imports the System namespace, allowing the use of various classes and functionalities provided by the .NET Framework.
The program defines a new namespace called myApp, which is a way to organize code and prevent naming conflicts with other code.
Inside the myApp namespace, there is a class called Program. This class contains the program's entry point - the Main method, which is the starting point of execution for any C# application.
Inside the Main method, three integer variables i, j, and k are declared, which will be used as loop counters.
A character array alpha is initialized with the string "ABCDEFGHIJKLMNOPQRSTUVWXYZ". The ToCharArray() method converts the string into an array of characters, so each element of the alpha array will contain one letter of the alphabet.
The program enters a nested loop with a for loop for variable i, ranging from 0 to 4, inclusive. This loop controls the rows of the output pattern.
Inside the i loop, another for loop for variable j is used, ranging from 0 to 4, inclusive. This loop controls the columns of the output pattern.
Inside the j loop, there is an if-else statement. If i is equal to j, the letter corresponding to the index j in the alpha array is printed using Console.Write(alpha[j]), otherwise, a space is printed.
After the j loop, there is another for loop for variable k, ranging from 3 to 0, inclusive. This loop controls the columns of the second part of the output pattern.
Inside the k loop, there is another if-else statement. If i is equal to k, the letter corresponding to the index k in the alpha array is printed using Console.Write(alpha[k]), otherwise, a space is printed.
After printing the row, a new line is created using Console.WriteLine() to move to the next row in the output pattern.
Steps 6 to 11 are repeated four more times, as i ranges from 0 to 4.

💯 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.
