Overloading − a type of polymorphism in which some or all of operators have different implementations depending on the types of their arguments. For example function name will remain same but it take different number of arguments and can do different task. Polymorphism − This is an object oriented concept where same function can be used for different purposes. This is also called a subclass or derived class. This is also called a base class or super class.Ĭhild Class − A class that inherits from another class. Parent class − A class that is inherited from by another class. Here child class will inherit all or few member functions and variables of a parent class. Inheritance − When a class is defined by inheriting existing function of a parent class then it is called inheritance. Member function − These are the function defined inside a class and are used to access object data.

These variables are called attribute of the object once an object is created.

This data will be invisible to the outside of the class and can be accessed via member functions. Member Variable − These are the variables defined inside a class. You define a class once and then make many objects that belong to it. Object − An individual instance of the data structure defined by a class. You can think of a class as a template for making many instances of the same kind (or class) of object. Object Oriented Conceptsīefore we go in detail, lets define important terms related to Object Oriented Programming.Ĭlass − This is a programmer-defined data type, which includes local functions as well as local data. Same way there is object oriented programming concepts which assume everything as an object and implement a software using different objects. Similarly we can imagine our car made of different objects like wheel, steering, gear etc. We can imagine our universe made of different objects like sun, earth, moon etc.
