Sample Solution:-

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise9  // Declaration of the Exercise9 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        int i, j, rows;  // Declaration of variables 'i', 'j' for iteration, 'rows' to store the number of rows

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Display the pattern like a right angle using asterisk:\n");  // Displaying the purpose of the program
        Console.Write("------------------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");   

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

        for (i = 1; i <= rows; i++)  // Loop to iterate through each row
        {
            for (j = 1; j <= i; j++)  // Loop to print '*' in each row based on the value of 'i'
            {
                Console.Write("*");  // Displaying asterisks to form the pattern
            }
            Console.Write("\n");  // Moving to the next line to form the right-angled pattern
        }
    }   
}

Sample Output:

Display the pattern like right angle using asterisk:
