What are the differences between C and C++?

Answer 1

C is a procedure oriented language, a C program would consist of modular approach (usage of functions).
C++ is an object oriented programming language (OOPS!),which facilitates usage of classes and objects, overloading, inheritance features along with the C language features.
Hence the name C++, which indicates that it is an incremented version of C ( post increment operator ++) with additional OOP feature added to C.
