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.This is the main different between c and c++.

The main difference lies in the fact that C++ is an object oriented programming language. User Defined datatypes called classes can be used in C++; but such datatypes cannot be used in C.

 The basic difference is that C is a procedural language, while C++ is a OOP language. So all the OOPs concepts like Data Hiding, Data Encapsulation, Data Abstration, Inheritance and Polymorphism can be implemented using C++. All these make the complex programming task handling easy.

But this doesn't mean that C is a lower grade language. It has its own beauty, as the codes written using C can be more compact. It uses pointers extensively, while C++ has got a "reference" which has wide use replacing pointers.

Pointers make direct memory address easy, and so C is still used to write programs for embedded systems.

• 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.

• C structures have a different behaviour compared to c++ structures. Structures in c do not accept functions as their parts.

• 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 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().

• 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.

• 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++.
