What is the difference between C and C++?

[GaMeR-BoY]

Hello all, I am learning programming languages, I have started with C and next in the Syllabus is C++. But i don't know what is the difference between them, can anyone explain me What is the difference between C and C++? Thanks in advance...

C++ is a programming language based on obkect oriented model [not a complete object oriented programming language]. While C is a procedural programming language, C emphasizes more on procedure rather then data, while C++ is data emphasized... There are a lot of more difference, its better you refer book on it...

Undeclared functions in c++ are not allowed. The function has to have a prototype defined before the main() before use in c++ although in c the functions can be declared at the point of use.

In C++ identifiers are not allowed to contain two or more consecutive underscores in any position. C identifiers cannot start with two or more consecutive underscores, but may contain them in other positions. C input/output is based on library and the processes are carried out by including functions. C++ i/o is made through console commands cin and cout. C does not have any classes or objects. It is procedure and function driven. There is no concept of access through objects and structures are the only place where there is a access through a compacted variable. c++ is object oriented.

[Bracken]

C structures have a different behaviour compared to c++ structures. Structures in c do not accept functions as their parts. C functions do not support overloading. Operator overloading is a process in which the same function has two or more different behaviours based on the data input by the user. C does not support new or delete commands. The memory operations to free or allocate memory in c are carried out by malloc() and free().

* After declaring structures and enumerators in c we cannot declare the variable for the structure right after the end of the structure as in c++.
* For an int main() in c++ we may not write a return statement but the return is mandatory in c if we are using int main().
* In C++ identifiers are not allowed to contain two or more consecutive underscores in any position. C identifiers cannot start with two or more consecutive underscores, but may contain them in other positions.
* C has a top down approach whereas c++ has a bottom up approach.
* In c a character constant is automatically elevated to an integer whereas in c++ this is not the case.
* In c declaring the global variable several times is allowed but this is not allowed in c++.

Actually c is a procedural programming language which cann't face the real world problem. It has some drawback like a global data is shared by all function and if in a large program it is find out difficult that which function uses which data.

On the other hand c++ is an object oriented programming language which eliminate some pitfall of conventional or procedural programming language. It is a concept or approach for designing a new software. It is nothing to do with any programming language although a programming language which support the oops concept to make it easier to implement.
