C# Star Pattern 11

Here`s a program that prints the above star 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++) {
        for (j = i; j <= 5; j++)
          Console.Write("*");
        for (k = 1; k < (i * 2) - 1; k++)
          Console.Write(" ");
        for (j = i; j <= 5; j++)
          Console.Write("*");
        for (k = 1; k < i * 2; k++)
          Console.Write(" ");
        Console.WriteLine();
      }
      for (i = 4; i >= 1; i--) {
        for (j = 5; j >= i; j--)
          Console.Write("*");
        for (k = 1; k < (i * 2) - 1; k++)
          Console.Write(" ");
        for (j = 5; j >= i; j--)
          Console.Write("*");
        for (k = 1; k < i * 2; k++)
          Console.Write(" ");
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

**********
****  ****
***    ***
**      **
*        *
**      **
***    ***
****  ****
**********

🧠 How the Program Works

Let's break down the logic behind the code:

Import the required namespace: using System;. This allows the program to use classes and methods defined in the System namespace.
Define a new namespace called myApp. Namespaces are used to organize code and prevent naming conflicts with other code.
Inside the myApp namespace, declare a class named Program. This class contains the Main method, which is the entry point of the program.
Inside the Main method, declare three integer variables i, j, and k without initializing them.
Start the first loop with the statement for(i=1; i<=5; i++). This loop iterates from i = 1 to i = 5, and in each iteration, it does the following:
1. Start a nested loop with for(j=i; j<=5; j++). This loop prints * 5 - i + 1 times. For i = 1, it prints 5 *, for i = 2, it prints 4 *, and so on.
2. Start another nested loop with for(k=1; k<(i*2)-1; k++). This loop prints 2 * i - 1 spaces. For i = 1, it prints 1 space, for i = 2, it prints 3 spaces, and so on.
3. Start the third nested loop with for(j=i; j<=5; j++). This loop prints * 5 - i + 1 times, similar to the first nested loop.
4. Start the fourth nested loop with for(k=1; k<i*2; k++). This loop prints 2 * i spaces. For i = 1, it prints 2 spaces, for i = 2, it prints 4 spaces, and so on.
5. After the nested loops, a new line is written using Console.WriteLine() to move to the next row.
After the first set of nested loops, there's another loop with for(i=4; i>=1; i--). This loop iterates from i = 4 to i = 1, and in each iteration, it does the same pattern as described in step 5 but in reverse order. It prints the pattern of * and spaces in decreasing order.
The program execution ends after the second set of nested loops finishes, and the program terminates.

💯 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.
