What is Destructor in C++?

Destructor in c++ is a member function that works opposite to constructor (it deletes the objects of classes).

 

Syntax of destructor

~name_of_constructor()  //tilde sign(~)

Properties of Destructor in C++

• Like a constructor, it is invoked automatically.
• It must have the same name as the class name.
• The destructor doesn't declare as static and has no argument.
• It has no return type, as well as destructor address, can't be accessed.

Note

There is only one destructor in a class with class name preceded by ~

Example of Destructor in C++

A simple example of destructor in c++ is given below:

#include <iostream>  
using namespace std;  

class TIH  
 {  
   public:  
        TIH()    
        {    
            cout<<"Constructor is here"<<endl;    
        }    
        ~TIH()    // defination of destructor
        {    
            cout<<"Destructor is present"<<endl;    
        }  
};  

int main()   
{  
    TIH t1; //creating an object of TIH 
    TIH t2; 
    return 0;  
}  

OUTPUT

Constructor is here

Destructor is present
