C#: Display the pattern like right angle triangle with number increased by 1

Last update on December 20 2024 12:49:49 (UTC/GMT +8 hours)

Write a C# Sharp program to make such a pattern like a right angle triangle with the number increased by 1.
The pattern is as follows :

1
2 3
4 5 6
7 8 9 10

Sample Solution:-

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise12  // Declaration of the Exercise12 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        int i, j, rows, k = 1;  // Declaration of variables 'i', 'j' for iteration, 'rows' to store the number of rows, 'k' to store and increase the number

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Display the pattern like a right-angle triangle with numbers increased by 1:\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 the incremented value of 'k' in each row 'i' times
            {
                Console.Write("{0} ", k++);  // Displaying 'k' and incrementing 'k' by 1 for each iteration
            }
            Console.Write("\n");  // Moving to the next line to form the right-angled pattern
        }
    }
}

Sample Output:

Display the pattern like right angle triangle with number increased by 1:                                     
---------------------------------------------------------------------------                                                                           
Input number of rows : 5                                                                                      
1                                                                                                             
2 3                                                                                                           
4 5 6                                                                                                         
7 8 9 10                                                                                                      
11 12 13 14 15
