Newbie programmers are always in confusion for what is the difference between c and c++. In this article, we have explained it in very simple language.
What is Programming Language?
A programming language is a formal computer language or constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
There are various programming languages in existence as of today, but we’ll see today that what is the difference between C and C++? Come let’s check it out below :
Basic Introduction for C and C++ Programming language :
- C programming language was developed by Dennis Ritchie while C++ programming language was developed by Bjarne Stroustrup.
- C++ is the derived form of C programming language. C is the subset of C++.
- The major difference between C & C++ is that C does not support classes and objects as C is a procedural programming language, while on the other side C++ is a combination of both procedural and object-oriented programming language.
- The following table contains some of the major differences between C and C++.
Difference between C and C++ Programming
|1] C is a procedural [structural] programming language.||1] C++ is a procedural also an object oriented programming language.|
|2] C supports only built-in data types.||2] C++ supports both built-in and user defined data types.|
|3] Multiple declaration of global variables are allowed but variables must have to be defined at the beginning in the function.||3] Multiple declaration of global variables are not allowed but variables can be defined anywhere in the function.|
|4] No virtual Functions are present in C.||4] The concept of virtual Functions are used in C++.|
|5] C follows top-down approach.||5] C++ follows bottom-up approach.|
|6] Operator over-loading isn’t possible in C.||6] C++ allows operator over-loading.|
|7] Name space feature isn’t there in C Programming language.||7] Name space feature is used in C++ to avoid name collision.|
|8] Here,scanf() Function is used for input.|
Printf() Function is used for output.
|8] Here, Cin>> Function is used for input.|
Cout<< Function is used for output.
|9] malloc() and calloc() Function is used for memory allocation.|
free() Function is used for memory de-allocation.
|9] new operator is used for memory allocation.|
free operator is used for memory de-allocation.
|10] In C, Polymorphism is not possible.||10] In C++, Polymorphism is used, as Polymorphism is the important feature of OOPS.|
|11] In C, inheritance is not possible.||11] In C++, inheritance is possible.|
|12] Exception handling is not present.||12] Try and Catch block is used for Exception handling.|
|13] Mapping between data & functions is difficult in C.||13] Data & functions are easily mapped through “objects”.|
|14] C is a mid-level programming language.||14] C++ is a high-level programming language.|
We have also included a video below which clearly mentions the difference between C and C++ programming.
