Exp02-CSharpPattern

Aim:

To write the C# program to print Pascal's triangle.

Algorithm:

Step1:

Initialize the neccessary attributes.

Step2:

Get the no. of rows from the user.

Step3:

Using for loop print the rows, columns and spaces at required places.

Step4:

Apply if condition to print 1.

Step5:

If the condition fails, print the number using the formula. value=value*(i-j+1)/j.

using System;
public class Pattern {
   class Example {
      public static void Main() {
         int rows, c = 1, s, i, j;
         rows=Convert.ToInt32(Console.ReadLine());
         Console.WriteLine("Pascal's triangle");
         for(i = 0; i<rows; i++) {
            for(s = 1; s <= rows-i; s++)
            Console.Write(" ");
            for(j = 0; j <= i; j++) {
               if (j == 0||i == 0)
               c = 1;
               else
               c = c*(i-j+1)/j;
               Console.Write(c + " ");
            }
            Console.WriteLine();
         }
      }
   }
}

Output:

Result:

Hence, a C# program for a pascal's triangle is executed successfully.
