C  Language Vs. C++ Language

 

C Language

C++ Language

Language

 ‘C’ is a procedure Oriented language. ‘C++’ is an object oriented language.

Founder

‘C’ language is developed by Dennies Ritchie. ‘C++’ language is developed by Bjarne Stroustrup.

Approach

 ‘C’ language follows top-down approach. ‘C++’ follows bottom up approach.

OOPS Concepts

 As ‘C’ language is procedure oriented language, it does not support OOPS concepts such as class, object, Inheritance, Polymorphism, Data hiding,etc. C++ is an object oriented language hence supports class, object, data hiding, polymorphism, Inheritance, abstraction, etc..

Focus

 C focus on method or process rather than data. C++ focuses on data rather than method or procedure.

Building Blocks

 Building blocks of ‘C’ language are : functions. Building blocks of ‘C++’ language are : objects.

Input-output

 ‘C’ language uses scanf() and printf() for input and output. ‘C++’ language uses cin>> and cout<< operators for input and output.

Virtual functions & Reference Variable

 ‘C’ language does not support virtual functions and reference variables. ‘C++’ language supports virtual functions & reference variables.

Exception Handling

 It does not support exception handling It supports exception handling using try and catch block.

Declaration of variables

 It require to declare all the variables at the top of the program. It allows to declare variable anywhere in the program before use.

Memory functions

 ‘C’ language uses calloc(), malloc() and free() functions for allocating and de-allocating memory. ‘C++’ language uses operators new and delete for the same purpose.

File Extension

 ‘C’ program has file extension .c ‘C++’ program has file extension .cpp
