C# Alphabet Pattern 29

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

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by importing the required namespace System.
The program defines a namespace myApp and declares a class named Program within that namespace.
Inside the Program class, the Main method is declared. This is the entry point of the program, and it is where the execution will begin.
Two integer variables i and j are declared to be used as loop counters later in the program.
An integer variable k is initialized with the value 4.
An array of characters alpha is created and initialized with the English alphabet uppercase letters. Each letter is stored as an individual element in the array.
The program starts the first loop with the for statement: for(i=k; i>=0; i--). This loop will iterate k + 1 times, with i taking values from k to 0.
Inside the first loop, another loop is nested using the for statement: for(j=k; j>=0; j--). This loop will also iterate k + 1 times, with j taking values from k to 0.
Within the nested loops, there is an if condition: if (j > i). If this condition is true, it means that the current value of j is greater than the current value of i.
If j > i, the program will print the character alpha[j], which corresponds to the letter at the j-th index in the alpha array. Otherwise, it will print the character alpha[i].
The program uses Console.Write to print characters without appending a new line.
After the nested loops, the program uses Console.WriteLine to add a new line and move to the next line of output.
The same pattern is repeated again with a slight variation in the loops and conditions to print the upper half of the pattern.
After completing the upper half of the pattern, the program enters a new loop with i going from 1 to k, to print the lower half of the pattern.
The lower half of the pattern is printed following the same logic as the upper half, but in reverse order.
After printing the entire pattern, the Main method execution ends, and the program terminates.

💯 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.
