An object in C++ is a particular instance of a class. It is generated using the class’s constructor function and, aside from having its own set of data and functions, is just a duplicate of the class. Using the Person class’s previous example, here is how to build a Person class ob...
template <typename T> void val_func(T t) {} val_func(nullptr); // deduces T = nullptr_t val_func((int*)nullptr); // deduces T = int*, prefer static_cast though 5️⃣ Conversion to bool from nullptr_t From cppreference :- In the context of a direct-initialization, a bool...
A friend function is a non-member function, to make a function a friend of a class, we declare class function with prefixing keyword friend.
Static variable retains its value while non-static or dynamic variable is initialized to '1' every time the function is called. Hope that helps. reference: http://stackoverflow.com/questions/5255954/what-is-the-difference-between-static-and-normal-variables-in-c...
staticvoidSetVerbosity(LogPriority new_priority){ verbosity = new_priority; } This allows the level of detail in the log to be changed dynamically. This is a great way to abstract away unnecessary information from end users without removing the developer’s ability to effectively debug. ...
It is possible to have static member functions in a class in the same way as static data members. The static member function(s) is similar to the normal member function(s) of a class, but the only difference is that it can access only static member(s) (data or functions) declared in...

It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the data member as pointer to object of similar class, then it is called a self-referential class.
