C# Number Pattern 28

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 = 10; i >= 1; i--) {
        for (j = i; j < 10; j++)
          Console.Write(j);
        Console.Write("0");
        for (k = 9; k >= i; k--)
          Console.Write(k);
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

0
909
89098
7890987
678909876
56789098765
4567890987654
345678909876543
23456789098765432
1234567890987654321

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including the necessary namespace System.
The program declares a new namespace called myApp.
Inside the myApp namespace, there is a class called Program.
The Program class has a static method Main, which is the entry point of the program. It takes a string array args as a parameter, although in this program, it is not being used.
Three integer variables i, j, and k are declared to be used in the following loops.
The outer for loop is used to iterate from i=10 down to i=1. It starts with i=10, and in each iteration, it decreases i by 1 until i becomes 1.
Inside the outer for loop, there are two nested for loops and a Console.WriteLine() statement.
The first nested for loop is used to print the numbers from i to 9. The loop starts with j having the value of i and increases j by 1 in each iteration until it reaches 9. During each iteration, it prints the value of j using Console.Write(j).
After the first nested for loop, there is a Console.Write("0") statement. This statement prints the number "0" after printing the values from i to 9.
The second nested for loop is used to print the numbers from 9 to i. The loop starts with k having the value of 9 and decreases k by 1 in each iteration until it becomes equal to i. During each iteration, it prints the value of k using Console.Write(k).
Finally, after both nested loops, a Console.WriteLine() statement is used to move the cursor to the next line, creating a new line for the next iteration of the outer loop.
The outer loop continues its iterations until i becomes 1, and the program prints the respective pattern in each iteration.

💯 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.
