Difference between C and C++ programming languages

C and C++ are among the most popular programming languages used for developing system applications, games, operating systems, etc. Both sound similar but have differences in terms of the features that they provide.

In this article, I will discuss the similarities and differences between C and C++ programming languages.

What is C programming language?

C is a general-purpose, structural, or procedure-oriented computer programming language. It was developed in the 1970s by Dennis Ritchie at Bell Laboratories.

C is a machine-independent language which means code written on one machine can run on another with some minor machine-specific changes if required. The development of many other modern programming languages is inspired by C which includes C++, Java, etc.

MS Windows, Linux Kernel, Oracle database, Git, and Python interpreter are some examples of applications that are developed using the C programming language.

What is C++ programming language?

C++ is considered an extension of the C programming language, sometimes it is called C with classes. It is a high-level, general-purpose, object-oriented programming language developed by Bjarne Stroustrup in the 1980s.

It is used for developing complex high-performance applications. It is used in the development of some well-known applications like youtube, Windows OS, Mozilla Firefox, MySQL, etc.

Similarities between C and C++ programming languages

The similarities between C and C++ are –

  • Both have the same basic syntax
  • Nearly all the operators and keywords of C are present in C++ and they have the same function
  • Compilation and execution of the program are similar
  • The basic memory model of both the languages is very close to the hardware
  • Both languages have the same notions of the stack, heap, file-scope, and static variables
  • Both languages are used in developing high-performance real-time applications

C vs C++ : The key differences

The key differences between C and C++ are given in the below table.

C is structural or procedural programming languageC++ is an object oriented programming language
Developed by Dennis Ritchie in 1970s at AT&T Bell Labs.C++ was developed by Bjarne Stroustrup in 1979 at Bell Laboratries
C is subset of C++C++ is a superset of C
Data is less secured in C as compared to C++In C++, you can use access modifiers for class members to make it inaccessible for outside users.
It follows the top-down approachC++ follows the bottom-up approach
Function overloading is not supported in CC++ supports function overloading
Operator overloading is not possible in CYou can overload operators in C++
You can not defined functions inside structureYou can define functions inside structure
Doesn't provide feature of namespace It has namespace feature
Exception handling is not easyIt provides try and catch block for exception handling
Programs are divided into procedures and modulesPrograms in C++ are divided into functions and classes
