Instructions

1. Arithmetic Operations

   • Accepts two numbers and performs basic arithmetic operations such as addition, subtraction, multiplication, division, modulus, exponentiation, and exponential.

2. Check Armstrong Number

   • Validates whether a given number is an Armstrong number.

3. Find Substrings

   • Takes a user input string and prints all possible substrings.

4. Divide by Zero Exception

   • Demonstrates a try-catch block for handling a DivideByZeroException.

5. Pascal's Triangle

   • Generates and prints Pascal's Triangle based on the user-specified number of rows.

6. Floyd's Triangle

   • Generates and prints Floyd's Triangle based on the user-specified number of rows.

7. Read File

   • Reads and displays the content of a text file using different approaches, such as File.ReadAllText(), File.ReadAllLines(), and StreamReader.

8. Stack Operations

   • Implements a basic stack with operations like push, pop, peek, and display.

9. Complex Number Operations

   • Takes two complex numbers as input, performs addition, and displays the result.

10. Shapes Drawing and Erasing

    • Illustrates polymorphism by drawing and erasing various shapes (Circle, Triangle, Square, Rectangle).

11. Shapes Area and Perimeter

    • Calculates and displays the area and perimeter of different shapes (Circle, Triangle, Square, Rectangle).

12. Resize Rectangle

    • Allows the user to create a rectangle and then resize it by changing its width and height.

Running the Program

• Execute the Main() method in the Program class to start the program.
• Choose from the menu options by entering the corresponding number.

Note

• The program is structured using object-oriented principles, demonstrating the use of classes, interfaces, and inheritance.
• Some functionalities may prompt for user input, so follow the on-screen instructions.
