Write a C# Sharp program that takes a number and a width also a number. It then displays a triangle of that width using that number.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise2
{
    public static void Main()
    {
        // Prompt user to input a number
        Console.Write("Input a number: ");
        // Read and store the entered number
        int num = Convert.ToInt32(Console.ReadLine());

        // Prompt user to input the desired width
        Console.Write("Input the desired width: ");
        // Read and store the entered width
        int width = Convert.ToInt32(Console.ReadLine());

        // Initialize height to the value of width
        int height = width;

        // Loop through each row based on the given height
        for (int row = 0; row < height; row++)
        {
            // Loop through each column based on the given width
            for (int column = 0; column < width; column++)
            {
                // Print the number provided by the user
                Console.Write(num);
            }

            // Move to the next line after printing a complete row
            Console.WriteLine();

            // Decrement the width after each row is printed
            width--;
        }
    }
}

Sample Output:

Input a number: 2                                                                                             
Input the desired width: 5
