What are constructor and destructor explain it with syntax?

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.

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.

A destructor is a special member function that works just opposite to constructor , unlike constructors that are used for initializing an object, destructors destroy (or delete) the object. Syntax of Destructor ~class_name() { //Some code }

14. What is syntax of defining a destructor of class A? Explanation: A destructor starts with a ~(tilde) symbol, has the same name as the class . 15.
