Write a program in C# Sharp to display the pattern like a pyramid using asterisk and each row contain an odd number of asterisks.
The pattern is as below:

  *                                                                                                    
 ***

Sample Solution:

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise20  // Declaration of the Exercise20 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        int i, j, n;  // Declaration of variables of type integer

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Display the pattern like pyramid containing odd number of asterisks:\n");  // Displaying the purpose of the program
        Console.Write("----------------------------------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");

        Console.Write("Input number of rows for this pattern :");  // Prompting the user to input the number of rows for the pattern
        n = Convert.ToInt32(Console.ReadLine());    // Reading the number of rows entered by the user

        // Loop to print the pattern
        for (i = 0; i < n; i++)
        {
            for (j = 1; j <= n - i; j++)  // Loop to print spaces before the asterisks
                Console.Write(" ");

            for (j = 1; j <= 2 * i - 1; j++)  // Loop to print asterisks
                Console.Write("*");

            Console.Write("\n");  // Moving to the next line after printing each row of the pattern
        }
    }
}

Sample Output:

Display the pattern like pyramid containing odd number of asterisks:                                                                                           
----------------------------------------------------------------------                                                                                               
Input number of rows for this pattern :10                                                                                                         
         *                                                                                               
        ***                                                                                        
       *****                                                                                 
      *******                                                                                          
     *********
