Can you overload destructor for your class?

No. Classes can only have one destructor, whether you define one yourself or allow the compiler to generate one for you. The compiler-generated destructor is public by default, does not release any memory allocated to any class' member pointers, and is non-virtual, which are the three main reasons for defining your own.

When is a destructor called?

Destructors are called when an object is no longer used. In a language like C++, this is done explicitly by the programmer when the delete operator is used on the object.

A method that is automatically called when an instance of a class is created?

The constructor of a class is automatically called when an instance of the class is created (using new in C++). The constructor method has the same name as the class that it is a part of. Constructors have no type and do not return anything. Similarly, the destructor is automatically called when the instance of the class is destroyed. The destructor is the same name as the class and is preceded by a tilde (~) For example: class Example { public: Example() // Constructor { printf("Object created\n"); } ~Example() // Destructor { printf("Object destroyed\n") } }; int main() { Example* x = new Example(); // Creates object, calls constructor delete x; // Calls destructor, deletes object return 0; }


Can you declare a Destructor as Private?

When destructor can be virtual in c plus plus?

A class constructor initialises object member variables, ensuring the object is in a valid state from the point of instantiation. The destructor resets those same variables when the object falls from scope. Typically, the destructor is only required to release any memory allocated to any internal class pointers.


What is issue in throwing an exception in a destructor?

If a destructor throws an exception, the instance is left in an invalid state. When an exception is thrown, the destructor automatically terminates at the point of the throw, unwinding the call stack until an exception handler is found (if one is provided). However, any resources yet to be released by the destructor, including all the instance's base classes, cannot be destroyed. When writing your own destructors, it is important to never throw an exception. If an exception could be thrown from within your destructor, you must catch it and handle it within the same destructor -- you must not rethrow the exception.


What is the difference between destructors in c plus plus and c sharp?

In C# only class instances can have a destructor, whereas both class and struct instances can have a destructor in C++. While syntactically similar, a C++ destructor executes exactly as written, whereas a C# destructor merely provides the body of the try clause of the class' finalize method.
