Last update on December 20 2024 12:49:47 (UTC/GMT +8 hours)

Write a program in C# Sharp to display a pattern like a right angle triangle with a number.

Sample Output:

1
12
123
1234

Sample Solution:-

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise10  // Declaration of the Exercise10 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 as a right-angle triangle using numbers:\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 numbers in each row from 1 to 'i'
            {
                Console.Write("{0}", j);  // Displaying numbers to form the pattern
            }
            Console.Write("\n");  // Moving to the next line to form the right-angled pattern
        }
    }
}

Sample Output:

Display the pattern as right angle triangle using number:                                                     
-----------------------------------------------------------                                                   
                                                                                                              
Input number of rows : 10                                                                                     
1                                                                                                             
12                                                                                                            
123                                                                                                           
1234                                                                                                          
12345                                                                                                         
123456                                                                                                        
1234567                                                                                                       
12345678                                                                                                      
123456789
