Incrementing a … WebApr 6, 2024 · Conclusion: In summary, a custom assignment operator in C++ can be useful in cases where the default operator is insufficient or when resource management, memory allocation, or inheritance requires special attention. It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states.

WebApr 8, 2024 · Dynamic casting in C++ is used to cast a pointer or reference from a base class to a derived class at runtime. The "dynamic_cast" operator is used for this purpose. It checks if the object being casted is actually of the derived class type, and if not, it returns a null pointer or a null reference. This allows for safer casting and can be ...
