C# Number Pattern 42

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 = 1; j <= 5; j++) {
          if (i == 1 || i == 5 || j == 1 || j == 5)
            Console.Write("1 ");
          else
            Console.Write("  ");
        }
        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; statement, which includes the System namespace that provides fundamental classes and base types.
The program declares a new namespace called myApp. Namespaces are used to organize code and avoid naming conflicts.
Inside the myApp namespace, there is a class named Program. In C#, every program starts with a Main method, and that method must be defined inside a class. The Main method is the entry point of the program, meaning that it is the first code that gets executed when the program starts running.
The Main method takes a parameter of type string[], named args. This parameter allows command-line arguments to be passed to the program, although in this specific program, the args parameter is not used.
The Main method declares two integer variables: i and j. These variables will be used as loop counters in the following for loops.
The program uses a nested for loop structure to print a pattern of 5x5 squares on the console.
The outer loop (for(i=1; i<=5; i++)) runs from i=1 to i=5. This loop controls the rows of the pattern.
The inner loop (for(j=1; j<=5; j++)) runs from j=1 to j=5. This loop controls the columns of the pattern.
Inside the nested loops, there's an if condition that checks whether the current row (i) or the current column (j) is at the boundary (first or last row/column) of the 5x5 pattern.
If the condition is true, meaning it is at the boundary, the program prints "1 " (with a space) to the console. This will create a border made up of ones around the 5x5 pattern.
If the condition is false, meaning it is not at the boundary, the program prints two spaces (" ") to the console. This will create empty spaces inside the 5x5 pattern.
After completing one row, the program writes a new line (Console.WriteLine()) to move to the next line, starting a new row in the pattern.
The outer loop continues to run until i reaches 5, completing the 5x5 pattern.

💯 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.
