C# Alphabet Pattern 25

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;
      char k = 'A';
      for (i = 1; i <= 5; i++) {
        for (j = 5; j >= i; j--)
          Console.Write("{0, 2} ", k++);
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

A B C D E
F G H I
J K L
M N
O

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins with the using System; statement, which allows the program to use classes and functionality from the System namespace.
The namespace myApp block is defined. Namespaces are used to organize code and avoid naming conflicts. In this case, the code is inside the myApp namespace.
Inside the namespace, the class Program block is defined. This is the entry point of the program where the execution starts. The Program class contains the Main method.
The Main method is the entry point of the program. It is defined as static void Main(string[] args). The Main method takes an array of strings args, which can be used to pass command-line arguments to the program. However, in this specific program, args is not used.
Inside the Main method, three variables are declared: int i, int j, and char k. i and j are used as loop counters, and k is initialized with the character 'A'.
The program enters a nested loop, starting with the outer loop for(i=1; i<=5; i++). This loop runs five times because i starts at 1 and increments by 1 on each iteration, and the loop continues as long as i is less than or equal to 5.
Inside the outer loop, there is another loop: for(j=5; j>=i; j--). This loop is responsible for printing the characters in reverse order from 'A' to the character corresponding to the current value of i.
The loop body contains Console.Write("{0, 2} ", k++);. It prints the current value of k with two spaces of padding and then increments k. As a result, each time the loop runs, it prints the next character after 'A'.
After the inner loop, Console.WriteLine(); is called to move the cursor to the next line, creating a new line for the next iteration of the outer loop.
The outer loop continues until i becomes 6, at which point the condition i<=5 becomes false, and the program exits the outer loop.
The Main method completes its execution, and the program finishes.

💯 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.
