README for Advanced Calculator Program This document provides detailed instructions on compiling, running, and using the Advanced Calculator Program. It also includes example inputs and expected outputs to help you understand how the program works. Overview The Advanced Calculator Program performs a variety of mathematical operations, including basic arithmetic (addition, subtraction, multiplication, division), advanced operations (exponents, square roots), and trigonometric and logarithmic calculations. The menu-driven interface allows users to select their desired operations and input values easily. Requirements  To run the program, you need the following:  C++ Compiler: Any C++ compiler (e.g., GCC, Clang, or MSVC).  Operating System: Works on Linux, macOS, or Windows (ensure you have a terminal). How to Compile the Program

1. Save the program code in a file named calculator.cpp.
2. Open your terminal or command prompt.
3. Navigate to the directory containing calculator.cpp.
4. Use the following command to compile the program: G++ calculator.cpp -o calculator This command creates an executable file named calculator. If you encounter errors during compilation, ensure your C++ compiler is correctly installed. How to Run the Program
5. After successful compilation, execute the program with the following command: ./calculator On Windows, you may need to run calculator.exe instead.
6. Follow the instructions displayed on the screen to perform calculations. Using the Program When you run the program, you will see the following menu: ======================== Calculator Menu ======================== What type of operation do you want? Choose from the following options:

13. Enter the number corresponding to your desired operation.
14. Follow the prompts to input the required values.
15. The program will display the result.
16. To perform another operation, choose an option from the menu again.
17. Enter 0 to exit the program. Examples of Inputs and Expected Outputs Here are some examples to demonstrate how to use the program: Menu Choices and Corresponding Inputs/Outputs:
18. Addition (Choose 1) Input: Enter two numbers: 10 5 Output:15
19. Subtraction (Choose 2) Input: Enter two numbers: 10 5 Output:5
20. Multiplication (Choose 3) Input: Enter two numbers: 10 5 Output:50
21. Division (Choose 4) Input: Enter dividend and divisor: 10 2 Output:5 If the divisor is zero: Input: Enter dividend and divisor: 10 0 Output: Error: division by zero is not allowed.
22. Exponential (Choose 5) Input: Enter the base and the exponent: 2 3 Output:8
23. Square Root (Choose 6) Input: Enter a number: 16 Output: 4 If the number is negative: Input: Enter a number: -16 Output: Invalid input: negative numbers cannot have square roots.
24. Sine (sin) (Choose 7) Input: Enter a value of angle in degree: 30 Output: 0.49999 (approximately 1/2)
25. Cosine (cos) (Choose 8) Input: Enter a value of angle in degree: 30 Output: 0.866 (approximately √3/2)
26. Tangent (tan) (Choose 9) Input: Enter a value of angle in degree: 45 Output: 1
27. Cosecant (csc) (Choose 10) Input: Enter a value of angle in degree: 30 Output: 2 (since csc(30°) = 1/sin(30°) = 2)
28. Secant (sec) (Choose 11) Input: Enter a value of angle in degree: 60 Output: 2 (since sec(60°) = 1/cos(60°) = 2)
29. Cotangent (cot) (Choose 12) Input: Enter a value of angle in degree: 45 Output: 1 (since cot(45°) = 1/tan(45°) = 1)
30. Arcsine (arcsin) (Choose 13) Input: Enter a value: 0.5 Output: 0.5236 (approximately 30°)
31. Arccosine (arccos) (Choose 14) Input: Enter a value: 0.5 Output: 1.0472 (approximately 60°)
32. Arctangent (arctan) (Choose 15) Input: Enter a value: 1 Output: 0.7854 (approximately 45°)
33. Logarithm (log) (Choose 19) Input: Enter the number and base of logarithm: 8 2 Output: 3 (since log(8) base 2 = 3)
34. Natural Logarithm (ln) (Choose 20) Input: Enter a number: 20 Output: 2.9957 (approximately ln(20)) Error Handling The program handles invalid inputs as follows: Error Handling Examples
35. Division by Zero: Input: Enter operation : 4 Enter first number: 5 Enter second number: 0 Output: Error: Division by zero is not allowed.
36. Negative Input for Square Roots: Input: Enter first number: -4 Output: Invalid input: Cannot compute the square root of a negative number.
37. Undefined Trigonometric Functions (Cosecant): Input: Enter operation :csc Enter first number (angle in radians): 0 Output: Error: Cosecant is undefined for this value.
38. Logarithm of a Negative Number: Input: Enter operation : log Enter first number: -10 Enter second number (base): 10 Output: Invalid input: Logarithm undefined for negative values.
