c-pattern's Introduction

EX-NO-3 Pattern

Aim:

To write a C# program for a pascal's triangle.

Equipment Required:

Microsoft Visual Studio 2022 (or Lower) or Any other C# compiler.

Algorithm:

Step 1:

Create a new Class named program.

Step 2:

Declare two variables of int data type one to store the input from user for no.of rows snd another the value for printing.

Step 3:

Get the number of rows from the user.

Step 4:

Using for loop print the rows and columns and space.

Step 5:

Check the first and last rows of the triange is 1 using if condition.

Step 6:

Otherwise use else to print the inner value val = val * (i - j + 1) / j

Step 7:

Print the program.

Step 8:

End of the Program.
