To use the data and access functions defined in the class, you need to create objects.Īccessing data members and member functions: The data members and member functions of class can be accessed using the dot(‘.’) operator with the object. The body of class is defined inside the curly brackets and terminated by a semicolon at the end.ĭeclaring Objects: When a class is defined, only the specification for the object is defined no memory or storage is allocated. an object is created) memory is allocated.Ī class is defined in C++ using keyword class followed by the name of class. When a class is defined, no memory is allocated but when it is instantiated (i.e.

In the above example of class Car, the data member will be speed limit, mileage etc and member functions can be apply brakes, increase speed etc.Īn Object is an instance of a Class.

Data members are the data variables and member functions are the functions used to manipulate these variables and together these data members and member functions defines the properties and behavior of the objects in a Class.

A Class is a user defined data-type which has data members and member functions.

So here, Car is the class and wheels, speed limits, mileage are their properties. There may be many cars with different names and brand but all of them will share some common properties like all of them will have 4 wheels, Speed Limit, Mileage range etc.

A C++ class is like a blueprint for an object.įor Example: Consider the Class of Cars.

It is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class.
