C Sharp Exercise: print Pascal triangle pattern

In this tutorial, we will discuss the title of C Sharp Exercise: print Pascal triangle pattern

In this post, we are going to learn how to display the pascal triangle number pattern in C# language using for and while loop,

Pascal triangle

Program to generate pascal’s triangle

Program to display pascal triangle Using for loop

Program 1

The program allows the user to enter the number of rows and then the program will show the pascal triangle number pattern using for loop in the C# programming language according to the rows

//Print pascal triangle number pattern
//using for loop
using System;
namespace PascalTriangle{
public class pascalPatternFor
{
    public static void Main(string[] args)
    {
        //decare variabes as integers
        int rowNo,i,j,num=1;
        
        //Take input from user
        Console.Write ("Enter the numbers To rows: ");
        rowNo=Convert.ToInt32( Console.ReadLine());
        //reading the input rom user
    
        //move to new line
         Console.WriteLine (" ");
         
         //dispay the pattern
         for(i=1; i<=rowNo; i++){
             //initialize first coefficient
             num=1;
             
             //print space
             for(j=1; j<=rowNo-i; j++)
                 Console.Write (" ");
                 
                 //print number 
                 for(j=1; j<=i; j++){
                 Console.Write (num+" ");
         //print number with spaces
                 //calculate the next coefficient
                 num=num*(i-j)/j;
             }
              //move to new iine   
               Console.WriteLine (" ");
    }
      Console.ReadKey();
}
}
}

When the above code is executed, it produces the following result

Output 1
