**There are mainly three programming languages :**

* **Machine level language**
    
    It is a set of instructions executed directly by the Computer’s CPU ( Central Processing Unit ).
    
* **Assembly level language**
    
    It is a low level programming language & it converted into executable machine code by an assembler.
    
* **High level language**
    
    It enables development of a program in much simple programming context language.
    
    It has a higher level of abstraction.

Programming Language

Hi, this series would cover all the topics of object oriented programming in c++ from basics to advance.


Procedure Oriented ( POP )	Object Oriented ( OOP )
It consist of writing a list of instruction or actions for the computer to follow and organizing these instruction into groups known as functions.	it is an way of modularizing programs by creating partitioned memory area for both data and functions that can be used as templates.
disadvantages are it has global data access , it does not model real world problem very well and there is no data hiding.	data is hidden and can’t be accessed by external functions , objects may communicate with each other through functions , new data and functions can be easily added.
