C# Number Pattern 62

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[, ] arr = new int[10, 10];
      int i, j, low = 0, high = 9, n = 1;
      for (i = 0; i < 5; i++, low++, high--) {
        for (j = low; j <= high; j++, n++)
          arr[i, j] = n;
        for (j = low + 1; j <= high; j++, n++)
          arr[j, high] = n;
        for (j = high - 1; j >= low; j--, n++)
          arr[high, j] = n;
        for (j = high - 1; j > low; j--, n++)
          arr[j, low] = n;
      }
      Console.WriteLine("Perfect Square Spiral");
      for (i = 0; i < 10; i++) {
        Console.WriteLine();
        for (j = 0; j < 10; j++)
          Console.Write("{0, 4}", arr[i, j]);
        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 by defining the namespace myApp and the Program class within it.
The Main method is the entry point of the program, which takes a string[] argument args but is not used in this program.
Inside the Main method, a 2-dimensional array arr of integers is declared with dimensions 10x10. This array will be used to store the perfect square spiral pattern.
Some variables are declared: i, j, low, high, and n. low and high are used to track the boundaries of the current spiral iteration, and n is used to store the values to be inserted into the spiral array.
The program enters a nested loop. The outer loop runs from i = 0 to i = 4 (for a total of 5 iterations). The low and high values are incremented and decremented in each iteration, respectively, to define the boundaries of the current spiral.
The first inner loop (for(j=low; j<=high; j++, n++)) populates the top row of the current spiral.
The second inner loop (for(j=low+1; j<=high; j++, n++)) populates the rightmost column of the current spiral.
The third inner loop (for(j=high-1; j>=low; j--, n++)) populates the bottom row of the current spiral.
The fourth inner loop (for(j=high-1; j>low; j--, n++)) populates the leftmost column of the current spiral.
Once the current spiral boundaries are processed, the outer loop increments i and the process repeats for the next spiral, until all 5 spirals are completed.
After the spiral pattern is generated and stored in the arr array, the program outputs the "Perfect Square Spiral" message.
The final loop (for(i=0; i<10; i++)) is used to print the arr array in a formatted manner, row by row, using Console.Write("{0, 4}", arr[i, j]). This format ensures that each number occupies 4 characters of space, making the output visually aligned.
The program ends 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.
