Brief History of C++ During 1970 Dennis Ritchie created C Programming language .  In the early 1980′s, also at Bell Laboratories, another programming language was created which was based upon the C language . New language was developed by Bjarne Stroustrup and was called C++ . Stroustrup states that the purpose of C++ is to make writing good programs easier and more pleasant for the individual programmer. C++ programming language is extension to C Language. In C we have already used increment operator (++) . Therefor we called C++ as “ Incremented C ” means Extension to C . Versions of C++ Language There are several versions of C++ Programming Language - Visual C++ Borland C++ Turbo C++ Standardize C++ [ANSI C++] History of C++ The C++ programming language has a history going back to 1979, when Bjarne Stroustrup was doing work for his Ph.D. thesis. One of the languages Stroustrup had the opportunity t...

Difference Between  Procedure Oriented Programming (POP) & Object Oriented Programming (OOP) Procedure Oriented Programming Object Oriented Programming Divided Into In POP, program is divided into small parts called  functions . In OOP, program is divided into parts called  objects . Importance In POP,Importance is not given to  data  but to functions as well as  sequence  of actions to be done. In OOP, Importance is given to the data rather than procedures or functions because it works as a  real world . Approach POP follows  Top Down approach . OOP follows  Bottom Up approach . Access Specifiers POP does not have any access specifier. OOP has access specifiers named Public, Private, Protected, etc. Data Moving In POP, Data can move freely from function to function in the system. In OOP, objects can move and communicate with each other through member functions. Expansion To add new data and function in POP is not so easy...
