C# Number Pattern 25

Here`s a program that prints the above number pattern using C# Programming:

example.cs

Copied

using System;

namespace myApp {
  class Program {
    static void Main(string[] args) {
      int i, j;
      for (i = 1; i <= 5; i++) {
        for (j = i; j <= 5; j++) {
          if (i < 4)
            Console.Write(i);
          else
            Console.Write(6 - i);
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; directive, which allows the program to use classes and methods defined in the System namespace.
The code defines a new namespace called myApp. Namespaces are used to organize and group related classes.
Inside the myApp namespace, there's a class named Program. This is the entry point of the program, and it contains the Main method, which is the starting point of execution in a C# program.
The Main method is declared with the signature static void Main(string[] args). It takes an array of strings as an argument, which can be used to pass command-line arguments to the program. However, in this specific program, the args array is not used.
Inside the Main method, two integer variables i and j are declared without any initialization.
The program enters a for loop with the variable i starting at 1 and ending when i becomes greater than 5. In each iteration, i is incremented by 1.
Inside the outer for loop, there is another for loop with the variable j starting at the value of i and ending when j becomes greater than 5. In each iteration, j is incremented by 1. This nested loop will print characters based on the value of i.
Inside the nested for loop, there is an if-else condition. The condition checks if the value of i is less than 4. If i is less than 4, it will execute the code inside the if block.
If i is less than 4, the program will print the value of i using Console.Write(i). Since the Console.Write method does not add a new line, the characters will be printed on the same line.
If i is not less than 4 (i.e., i is equal to 4 or 5), it will execute the code inside the else block.
Inside the else block, the program will print the value 6 - i. This will result in printing 2 when i is 4 and 1 when i is 5. Again, the Console.Write method is used to print these characters on the same line.
After the inner for loop completes, the program encounters Console.WriteLine();, which adds a new line after printing the characters in each row.
The outer for loop continues until i becomes greater than 5, printing rows of characters based on the value of i.

💯 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.
