If we don't write our own destructor in the class, the compiler generates one for us. Should start with a tilde(~) and same name of the class. 2) there cannot be more than one destructor in a class.

Here Is A Simple Method:


Whereas constructors are designed to initialize a class, destructors are designed to help clean up. Write a c++ program for a simple constructor and destructor. A destructor is called by the compiler when the.

Both Constructors And Destructors Are The Member Function Of The Class.


In this example, we have the class vect which represents a physical quantity a vector.the class consists of three components i, j and k.the methods of the class include the constructor vect() that sets all components to zero, a setvector method to set the value of the instance, a findmagnitude method to calculate the magnitude of the instance with. Set the student class the function body of the destructor of the meaning is changed to. Write a c++ program to depict execution of constructor and destructor.
