Difference between c and c++

History of C Language

The C programming language was designed by Dennies Ritchie in the early 1970s at Bell Laboratories. It was first used system implementation language for the nascent Unix operating system. The main reason to devised C was to overcome the limitations of B.  It was Derived from the type-less language BCPL ((Basic Combined Programming Language). C was was the evolution of B and BCPL by incorporating type checking. It was originally intended for use in writing compilers for other languages.

History of C++

C++ was devised by Bjarne Stroustrup in 1983 at Bell Laboratories. It is an extension of C by adding some enhancements to C language. Bjarne combined the simula's(a language designed for making simulations, created by Ole-Johan Dahl and Kristen Nygaard) features of object oriented and the efficiency of C. The new features added to language are templates, namespaces, exception handling and use of standary library.

Difference between c and c++

C++ is an extension of C language. This means that you can not only use the new features introduced with C++ but can also use the power and efficiency of C language. C and C++ are no more language for writing compilers and other languages, these general purpose languages are used worldwide in every field.
Here is a list of differences between c and c++.
The main difference between C and C++ is that C++ is object oriented while C is function or procedure oriented. Object oriented programming paradigm is focused on writing programs that are more readable and maintainable. It also helps the reuse of code by packaging a group of similar objects or using the concept of component programming model.  It helps thinking in a logical way by using the concept of real world concepts of objects, inheritance and polymorphism. It should be noted that there are also some drawbacks of such features. For example using polymorphism in a program can slow down the performance of that program.
On the other hand, functional and procedural programming focus primarily on the actions and events, and the programming model focuses on the logical assertions that trigger execution of program code.
