What is the difference between c and c++?

Firstly we need to know that C and C++ both are computer programming languages and the oldest surviving languages in the computers world. We use these computer programming languages as a medium of communication between user and computer.

So, with the help of these programming languages as instructions, the user instructs to the computer to perform some specific operation. Both languages are computer language, but both differ from each other in many terms.

So, we will learn about C first and later on about C++.





C language was developed by Dennis Ritchie in 1972. C++ language was developed Bjarne Strostroup in 1980.
It is a procedural oriented language. It is an object-oriented programming language.
C has a top to down approach. C++ has a bottom-up programming approach.
C solve big problems as modular programming. C++ solve big problems by dividing problems into class and object.
C does not support object-oriented programming therefore it has no support for polymorphism, encapsulation, and inheritance. Being an object-oriented programming language C++ supports polymorphism, encapsulation, and inheritance.
In C data and functions are separate and free entities. (because of procedural programming) In C++ data and functions are encapsulated together in the form of an object.
C does not have a namespace feature. C++ uses NAMESPACE which avoids name collision
In C, data are free entities and can be manipulated by outside code (doesn’t support information hiding). In C++, encapsulation hides the data.
C does not support function and operator overloading. C++ supports both function and operator overloading.
C does not allow functions to be defined inside structures. In C++, functions can be used inside a structure.
C does not support reference variables. C++ supports reference variables.

C Programming Language

C is a middle-level computer language developed by DENNIS RITCHIE in 1972 at Bell lab. C language contains features of low-level language as well as high-level language. C is a procedural oriented programming language and does not support classes and objects. In C programming language, a big problem divides into small pieces known as functions; this approach is known as Modular programming. We cannot declare a function as a member function of structure in C. C is the subset of C++.

C++ Programming Language

C++ is a programming language was developed by Bjarne Stroustrup in 1980. C++ language is a superset of the c language containing features of C language and Simula67. This language is introduced as the concept of class and objects. C++ is called as hybrid language as it is the combination of both procedural and object-oriented language. In C++ language big problems are divided into objects and classes.
