FEATURES OF C++


FEATURES OF C++

Classes and Objects:Class defines the properties of an object. It is the group of similar objects. It defines data member and member functions. Variables of the class are called objects, each object has it own separate memory. Object is also called instance of a class when it is initialized.

Encapsulation:It means binding of data members and member function in a class.
Data hiding: We always the data members as private and member functions as public. Private members are not accessible outside the class they can only be accessed through the public member functions.

Data Abstraction:We always define the essential properties of an object without going to the background details.
ADT(abstract data types): A class defines only the essential properties of an object without going to the background details.

Inheritance:We can inherit all the properties of a class instead of redefining all these properties again.
Hence, inheritance provides the programmer with following facilities:
1. Re-usability of code.
2. Saves programmers time and effort.
3. It increases the reliability.
4. It reduces the complexity.
5. It saves the memory and decreases the length of program.

Polymorphism:
Ability to have multiple forms one thing may perform multiple actions. For example: ‘+’ operator is used to add the sum of the two integers but we can also make it perform other functions like concatenation of the two strings.
