C++ allows us to use the three constructor functions we have discussed in the same class. For example: class complex { int a, b; public: complex() // default constructor { a= 10; b=45; }; complex( int x, int y) // parameterized constructor { a=x; b=y; }; complex( complex & v) // copy constructor { a=v.a; b=v.b; }; };

Destructors are called when an object gets destroyed . In Python, destructors are not needed as much as in C++ because Python has a garbage collector that handles memory management automatically. The __del__() method is a known as a destructor method in Python.

Read moreWhat are constructor and destructor explain it with syntax?
Constructors are special class functions which performs initialization of every object . The Compiler calls the Constructor whenever an object is created. Constructors initialize values to object members after storage is allocated to the object. Whereas, Destructor on the other hand is used to destroy the class object.
Read moreHow many types of destructor are there in C++?
There has to be only one Destructor in a class . A Destructor has no return type and no parameters. If we do specify a destructor in class then, the compiler creates a default destructor. The default destructor works fine unless memory is dynamically allocated or pointer is declared in the class.
Read moreWhat is destructor in C++ with example?
A destructor is a member function that is invoked automatically when the object goes out of scope or is explicitly destroyed by a call to delete . A destructor has the same name as the class, preceded by a tilde ( ~ ). For example, the destructor for class String is declared: ~String() .3 Ağu 2021
