C# Alphabet Pattern 30

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

💻 Testing the Program

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

Output

ABCDE
BABCD
CBABC
DCBAB
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; statement, which indicates that the code will be using classes from the System namespace, such as Console.
The myApp namespace is declared using namespace myApp. Namespaces help organize and group related classes and code together.
Inside the myApp namespace, there is a class called Program, which serves as the entry point for the program.
The Main method is the starting point of the program. It is declared as static void Main(string[] args), which means it is a static method that does not return any value and takes an array of strings (args) as input. The args parameter is used to pass command-line arguments to the program.
Three integer variables are declared: i, j, and k, which will be used in the following loops.
A character array named alpha is initialized with the English alphabet letters "ABCDEFGHIJKLMNOPQRSTUVWXYZ".
The program enters a for loop with the variable i ranging from 0 to 4. This loop is responsible for creating the pattern of characters.
Inside the outer loop, there are two nested for loops:
- The first nested loop, with the variable j, prints the characters from alpha array in reverse order. It starts with the current value of i and prints the characters until j becomes 0. For example, when i is 3, this loop will print "DCB".
- The second nested loop, with the variable k, prints the characters from the alpha array in regular order. It starts from 0 and goes up to 4 - i. For example, when i is 3, this loop will print "ABCDE".
After printing the pattern for each value of i, the program outputs a new line using Console.WriteLine() to move to the next line and start the next row of 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.
