C++ program to Display Student Details using constructor and destructor

What is Class and Objects in C++?

• Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
• The variables inside class definition are called as data members and the functions are called member functions.
• Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.

• Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
• Each object has different data variables. Objects are initialized using special class functions called Constructors.
