C vs c++
- 1. AND WITH FEATURES OF OOPS
- 2. In computing, C is a general-purpose programming language initially developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs. C is a procedural language in which we focus on mathematical and algorithm. Simple C Program # include <stdio.h> int main(void) { printf(“Hello Worldn”); return 0; }
- 3. C++ was originally developed to be the next version of C, not a new language. it was developed by Bjarne Stroustrup starting in 1979 at Bell Labs It is an object oriented programming language in which we focus on real life problem. Simple C++ Program #include <iostream.h> int main(void) { cout << “Hello Worldn”; return 0; }
- 4. Differences C it is most stable for handling small programme. C++ it is for handling large programme. C it follows top down approach. C++ it flows bottom up approach.
- 5. C Data in shareable mode. i.e. Data can be accessed by other function. C++ Data in non shareable mode. i.e. Data can not be accessed by other function. C It does not support function overloading (two functions may have the same name). C++ It support function overloading (function names must be unique). C Data is not secured in ‘c’ . C++ Data is secured in ‘c++’ .

- 7. OBJECTS Objects are basic runtime entity in object oriented system. When a program is executed, the objects interact by sending messages to one another . CLASS Classes are user defined data types and it behaves like built in types of programming language. It is the way to bind the data and function to gather in a single unit. INHERITANCE The mechanism of deriving a new class from an old class is called inheritance or derivation. The old class is known as base class while new class is known as derived class or sub class. The inheritance is the most powerful features of OOP.
- 8. POLYMORPHISM Polymorphism is a Greek term which means ability to take more than one form. For example, + is used to make sum of two numbers as well as it is used to combine two strings. DYNAMIC BINDING Dynamic binding means link exist between procedure call and code to be execute at run time when that procedure is call. MESSAGE PASSING Objects can communicate with each others by passing message same as people passing message with each other. Message passing involves name of object, name of function (message) and information to be send.
