Difference between constructor and method:

Constructor Method

The constructor functions are the special member functions which are designed to initialize the data members of a class. The constructor functions are automatically called by the compiler when declaring the object for the class. It is a collection of statements used for code reusability. These are also called as time savers as they save the time used to retype the code.

Constructor creates and initializes objects that don’t even exist yet Methods perform operations on the objects that already exist...
