C# Star Pattern 7

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 = 5; j >= 1; j--) {
          if (i == j)
            Console.Write("*");
          else
            Console.Write(" ");
        }
        for (k = 2; k <= 5; k++) {
          if (i == k)
            Console.Write("*");
          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:

First, the necessary namespace System is imported to use the Console class.
The program is declared within the myApp namespace.
Inside the Program class, the Main method is declared as the entry point of the program.
Three integer variables i, j, and k are declared. These variables will be used to control the loops and track the positions in the pattern.
The outer loop for(i=1; i<=5; i++) is responsible for controlling the number of rows in the pattern. It starts with i = 1 and iterates as long as i is less than or equal to 5. After each iteration, i is incremented by 1.
Inside the outer loop, there are two nested loops:
1. The first nested loop for(j=5; j>=1; j--) is responsible for printing spaces before the first asterisk (*). It starts with j = 5 and iterates as long as j is greater than or equal to 1. After each iteration, j is decremented by 1.
2. The second nested loop for(k=2; k<=5; k++) is responsible for printing spaces after the first asterisk (*). It starts with k = 2 and iterates as long as k is less than or equal to 5. After each iteration, k is incremented by 1.
Inside each of the nested loops, there is an if-else condition to determine whether to print an asterisk (*) or a space based on the current values of i, j, and k.
1. In the first nested loop (for(j=5; j>=1; j--)), the condition if(i == j) checks if the current row number i is equal to the value of j, which represents the position for printing the first asterisk (). If they are equal, a single asterisk () is printed using Console.Write("*"); otherwise, a space is printed using Console.Write(" ").
2. In the second nested loop (for(k=2; k<=5; k++)), the condition if(i == k) checks if the current row number i is equal to the value of k, which represents the position for printing the second asterisk (). If they are equal, a single asterisk () is printed using Console.Write("*"); otherwise, a space is printed using Console.Write(" ").
After the nested loops finish executing for a specific row, a new line is printed using Console.WriteLine() to move to the next row.
The outer loop continues until i becomes greater than 5, and the program execution finishes.

💯 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.
