Benefits of C++ over C Language

The major difference being OOPS concept, C++ is an object oriented language whereas C language is a procedural language.

Following features of C++ makes it a stronger language than C.

  • There is Stronger Type Checking in C++.

  • Exception Handling is there in C++.

  • All the OOPS features in C++ like Abstraction, Encapsulation, Inheritance etc makes it more worthy and useful for programmers.

  • C++ supports and allows user defined operators (i.e Operator Overloading) and function overloading is also supported in it.

  • Inline Functions in C++ instead of Macros in C language. Inline functions make complete function body act like Macro, safely.

  • The Concept of Virtual functions and also Constructors and Destructors for Objects.

  • Variables can be declared anywhere in the program in C++, but must be declared before they are used.
