In object oriented programming, a constructor is basically a function that is called when the object Is created. A destructor is called when the object is being destroyed (like going out of scope) class A { public: A() { std::cout << "A constructor called." << std::endl; } ~A()...
In the example above, a constructor is defined to accept an error message and a private member variable is used to store the error message. You can now throw instances of your exception class within your code using the throw keyword.Example To catch and handle the thrown exception, you can...
In addition to the above key points, the constructors also possess some additional features beyond the scope of the current topic. • We cannot access the address of the constructors. • An object with a constructor (or destructor) cannot be used as a member of a union. • Constructo...
A Destructor in C++ is a member function having the same name as that of the constructor. But, it is preceded by a tilde (~) symbol.

In simple words a "trivial" special member function literally means a member function that does its job in a very straightforward manner. The "straightforward manner" means different thing for different kinds of special member functions. For a default constructor and destructor being "trivial" means...
What is a memory leak in C++? What is the difference between delete and delete[ ]? What’s the difference between a class variable and an instance variable? Can static function access non-static members of class? Execution order of constructor and destructor in inheritance Does C++ support mul...

Previous versions of the compiler generated an explicit constructor and destructor for anonymous unions. These are deleted in Visual Studio 2015. C++ Copy struct S { S(); }; union { struct { S s; }; } u; // C2280 The preceding code generates the following error in Visual Studio ...
