C# Alphabet Pattern 34

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 = 4; j >= 0; j--) {
          if (i == j)
            Console.Write("{0}", alpha[j]);
          else
            Console.Write(" ");
        }
        for (k = 1; k <= 4; k++) {
          if (i == k)
            Console.Write("{0}", alpha[k]);
          else
            Console.Write(" ");
        }
        Console.WriteLine();
      }
      for (i = 3; i >= 0; i--) {
        for (j = 4; j >= 0; j--) {
          if (i == j)
            Console.Write("{0}", alpha[j]);
          else
            Console.Write(" ");
        }
        for (k = 1; k <= 4; k++) {
          if (i == k)
            Console.Write("{0}", alpha[k]);
          else
            Console.Write(" ");
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; statement, which allows the program to access classes and methods from the System namespace.
The namespace myApp statement declares a new namespace called "myApp," which helps organize the code and prevents naming conflicts with other namespaces.
Inside the namespace, there's a class called Program. This is the main class that contains the program's entry point, which is the Main method.
The Main method is declared as static void Main(string[] args). It is the entry point of the C# program, and it takes an array of strings (args) as input parameters.
Three integer variables are declared: i, j, and k. These will be used as loop counters in the following iterations.
A character array alpha is created and initialized with the characters "ABCDEFGHIJKLMNOPQRSTUVWXYZ". This array will be used to print letters of the alphabet.
The first for loop for(i=0; i<=4; i++) runs from i = 0 to i = 4 (inclusive), meaning it will have five iterations. This loop represents the rows of the pattern.
Inside the first for loop, there are two nested for loops, one for each half of the row.
1. The first nested loop for(j=4; j>=0; j--) runs from j = 4 to j = 0 (inclusive) and prints spaces if i is not equal to j. Otherwise, it prints the alphabet character at index j from the alpha array.
2. The second nested loop for(k=1; k<=4; k++) runs from k = 1 to k = 4 (inclusive) and prints spaces if i is not equal to k. Otherwise, it prints the alphabet character at index k from the alpha array.
After the nested loops, Console.WriteLine() is called to move to the next line, creating a new row for the pattern.
Once the first half of the pattern is printed, a similar process is repeated for the second half. A new for loop for(i=3; i>=0; i--) is used to print the remaining rows (from the fourth to the first).
Finally, the Main method ends, and the program execution completes.

💯 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.
