C# Alphabet Pattern 22

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 >= 1; j--) {
          if (j > i)
            Console.Write("  ");
          else
            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 indicates that the program will use classes from the System namespace.
The namespace myApp statement declares a new namespace called myApp, which is a logical container for the classes in the program.
Inside the myApp namespace, there is a class named Program, which contains the Main method. The Main method is the entry point of the program and will be executed first when the program runs.
Inside the Main method, three variables are declared and initialized:
- int i and int j are integer variables used as loop counters in the nested for loops.
- char k = 'A' initializes the character variable k with the letter 'A'. This variable will be used to print characters in the output.
The first for loop for(i=1; i<=5; i++) is used to iterate from i=1 to i=5, inclusive. This loop controls the number of rows in the output.
The second for loop for(j=5; j>=1; j--) is used to iterate from j=5 to j=1, inclusive. This loop controls the number of columns in each row of the output.
Inside the nested for loops, there is an if-else statement:
- if (j > i) checks if the column index j is greater than the row index i. If true, it means we are in the left part of the output triangle, and two spaces are printed using Console.Write(" ").
- If j <= i, we are in the right part of the output triangle, and the character k is printed using Console.Write("{0, 2}", k++). The {0, 2} format specifier ensures that the characters are right-aligned with a width of 2, which maintains proper spacing in the output.
After each row is printed, Console.WriteLine() is used to move to the next line, creating a triangular pattern of characters.
The program continues the iterations until all rows are printed with the characters 'A' to 'E' forming a right-angled triangle pattern.
When the program execution reaches the end of the Main method, it terminates, and the program finishes its execution.

💯 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.
