C#: Print the Floyd's Triangle

C# Sharp For Loop: Exercise-22 with Solution

Write a program in C# Sharp to print Floyd's Triangle. The Floyd's triangle is as below :

    1 
    01
    101 
    0101 
    10101 

Sample Solution:-

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise22  // Declaration of the Exercise22 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        int i, j, n, p, q;  // Declaration of variables i, j, n, p, q

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Print the Floyd's Triangle:\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
        n = Convert.ToInt32(Console.ReadLine());  // Reading the number of rows entered by the user

        // Loop to print the Floyd's Triangle pattern
        for (i = 1; i <= n; i++)
        {
            // Setting p and q values based on whether i is even or odd
            if (i % 2 == 0)
            {
                p = 1;
                q = 0;
            }
            else
            {
                p = 0;
                q = 1;
            }

            for (j = 1; j <= i; j++)
            {
                // Checking for even or odd position within the row to print p or q
                if (j % 2 == 0)
                    Console.Write("{0}", p);  // Printing p if j is even
                else
                    Console.Write("{0}", q);  // Printing q if j is odd
            }

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

Sample Output:

Print the Floyd's Triangle:
