Notes on C++

Return Value vs Reference

Understanding the difference between returning a value and a reference is crucial in C++. Returning a reference to a local variable leads to undefined behavior as the variable gets destroyed at the end of the function scope.

Polymorphism and Inheritance

Implementing polymorphism through base and derived classes allows for flexible and scalable code. For instance, using a base class `DynamicBoundaryMover` with derived classes like `SpringOscillator` and `SinusoidalMovement` enables diverse boundary behaviors in simulations.

Smart Pointers for Resource Management

Using smart pointers, such as `std::shared_ptr`, helps manage dynamic resources automatically, reducing memory leaks and dangling pointers.

Design Patterns in Simulation

Adopting design patterns like Strategy and Observer can enhance the structure and maintainability of simulation code, allowing for easier extension and modification.

Efficient Data Structures and Algorithms

Choosing the right data structures, like `std::unordered_map` for quick lookups, and algorithms significantly impacts the performance of simulations, especially in computationally intensive tasks.

File Parsing and Dynamic Configuration

Implementing robust file parsing logic is key to allowing dynamic configuration of simulations. This enables the setup of various simulation parameters and behaviors through external files.
