Differentiate smart pointers and raw pointers
Differentiate Smart Pointers and Raw Pointers
In C++, explain the fundamental differences between raw pointers and smart pointers. Compare and contrast common smart pointer types such as std::unique_ptr, std::shared_ptr, and std::weak_ptr with respect to their ownership semantics, lifetime management capabilities, and performance characteristics. Provide concrete examples illustrating appropriate use cases for each type, and discuss common pitfalls to avoid, such as double frees, memory leaks, and reference cycles.
