## Code Structure
|
|
|
|
### Calculator Class
|
|
The main calculator functionality is implemented in the `Calculator` class, which provides:
|
|
- Expression parsing and evaluation
|
|
- Mathematical function implementations
|
|
- Memory management
|
|
- Error handling
|
|
|
|
### Key Components
|

|
|
|
|
## Error Handling
|
|
|
|
The calculator includes comprehensive error handling for:
|
|
- Invalid expressions
|
|
- Division by zero
|
|
- Domain errors (logarithm of negative numbers, etc.)
|
|
- Memory overflow/underflow
|
|
- Syntax errors
|
|
|
|
Error messages are user-friendly and provide guidance for correct usage.
