Very long functions that can hardly run

One function containing another one or more functions inside it.

Two or more functions with the same name but different number of parameters or type.

Function with more than one form

Inheritance

Message passing

Encapsulation

Polymorphism

Do not use the same function name for two unrelated function

Overloading principle applies not only to functions, but to operators too

 It makes code much more readable

Perform different operations on the same operands.

Two functions having same number of argument, order and type of argument can be overloaded if both functions do not have any default argument.

Overloaded function must have default arguments.

Overloaded function must have default arguments starting from the left of argument list.

A function can be overloaded more than once.

Scope resolution operator

Arrow operator

Assignment operator

Equality operator

Function overloading

Function overriding

Operator overloading

Method overloading

Reusability of classes

Supports building extensible systems

It can hide instance variables and irrelevant methods of a class from other objects

Easy to maintain the code

Main()

str()

strcat()

strcpy()

Scalability

Encapsulation

Polymorphism

A name having one distinct meaning
