C# Number Pattern 18

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, k;
      for (i = 1; i <= 5; i++) {
        if (i % 2 == 0)
          k = 2;
        else
          k = 1;
        for (j = 1; j <= i; j++) {
          Console.Write(k + " ");
          k += 2;
        }
        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:

Importing the System namespace: The program starts with the using System; statement. This allows the code to use classes and functions from the System namespace, which contains fundamental types and classes like Console.
Creating the myApp namespace: The program defines a namespace called myApp. Namespaces help organize code and prevent naming conflicts.
Defining the Program class: Within the myApp namespace, there is a class named Program. This class contains the Main method, which serves as the entry point of the program.
Declaring variables: Inside the Main method, three integer variables are declared: i, j, and k. These variables will be used in the loops and other calculations.
Outer for loop: The program enters a for loop with i initialized to 1, and it will iterate as long as i is less than or equal to 5 (i <= 5). After each iteration, i is incremented by 1 (i++).
Inner if-else statement: Within the outer for loop, there's an if-else statement. It checks whether i is even (i % 2 == 0). If i is even, k is assigned the value of 2; otherwise, it is assigned the value of 1.
Inner for loop: After determining the value of k, the program enters an inner for loop with j initialized to 1. It will iterate as long as j is less than or equal to i (j <= i). After each iteration, j is incremented by 1 (j++).
Writing the output: Inside the inner for loop, the program prints the value of k followed by a space using Console.Write(k + " ");. Then, it increments k by 2 (k += 2) to get ready for the next iteration of the inner loop.
Newline: After completing the inner for loop, the program writes a newline character (\n) using Console.WriteLine();. This moves the output to the next line before the next iteration of the outer for loop.
Repeat: The outer for loop continues to iterate as long as the condition i <= 5 is true, and the inner loops are executed accordingly.

💯 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.
