Which constructors does a C++ class need? Which does it generates on its own? What about various assignment operators? And a destructor? How not to shoot ones leg off and navigate these waters effortlessly? This and more we cover in this video that tells us a simple rule to follow when implementing classes in Modern C++, the rule of "all or nothing". We dive into the reasons for its existence and see how it makes our lives easier. 📚 As always, the script to the video lives here: https://github.com/cpp-for-yourself/s...
