C++ Destructor

A destructor works opposite to constructor; it destructs the objects of classes. It can be defined only once in a class. Like constructors, it is invoked automatically.

A destructor is defined like constructor. It must have same name as class. But it is prefixed with a tilde sign (~).

Note: C++ destructor cannot have parameters. Moreover, modifiers can’t be applied on destructors.

C++ Constructor and Destructor Example

Let’s see an example of constructor and destructor in C++ which is called automatically.

 #include <iostream> using namespace std; class Employee  {    public:         Employee()           {               cout<<“Constructor Invoked”<<endl;           }           ~Employee()           {               cout<<“Destructor Invoked”<<endl;           } }; int main(void)  {     Employee e1; //creating an object of Employee      Employee e2; //creating an object of Employee     return 0; } 

Output:

Constructor Invoked Constructor Invoked Destructor Invoked Destructor Invoked
