In this tutorial you will learn about the C vs C++ and its application with practical example.
C vs C++
What is the difference between C and C++?
The major difference between C and C++ is that C is a procedural programming language and does not support the concept of classes and objects, while C++ is a combination of both procedural and object-oriented programming languages. C++ is considered a superset of C, which means C++ includes features of C programming language and in addition their own features.
| C | C++ |
|---|---|
| C is a procedural programming language. | C++ is a Object-Oriented Programming language. |
| C follows Top Down programming approach | C++ follows Bottom Up programming approach. |
| The extension of a C program file is .c | The extension of a c+ + program language is .cpp |
| C is a function driven language. | C++ is an object driven language. |
| In C, structure does not support declaring of function as its member | While, in C++ structure provides the feature of declaring a function as a member function. |
| C does not support inline function. | C++ supports inline function. |
| In C scanf and printf functions are used for standard input and output operation | In C++ cin and cout objects are for standard input and output operations. |
| C is not compatible with another language. | C++ is compatible with the other generic programming languages. |
| C does not support operator overloading. | C++ support operator overloading. |
| In C, the variable should be defined at the beginning of the program. | C++ allows you to declare variables anywhere in the function. |
| C does not support reference variables | C++ support reference variables |
| C does not allow you to use function overloading. | C++ allows you to use function overloading. |
| C language does not allows you to declare String or Boolean data types. It supports built-in and primitive data types. | C++ supports String and Boolean data types. |
| C does not support Exception Handling. However, it can be performed using some workarounds. | C++ supports Exception handling. Moreover, this operation can be performed using try and catch block. |
| Does not allows functions with default arrangements | Allow functions with default arrangements. |
| C does not have namespace feature. | It is present in the C++. |
| C is a subset of C++. It cannot run C++ code. | C++ is a superset of C. C++ can run most of C code. |
| Does not support encapsulation. As Data and functions are separate and free entities. | Supports encapsulation. Data and functions are encapsulated together as an object. |
| C does not support information hiding. In this language, data are free entities and can be changed outside code. | Encapsulation hides the data. So that data structures and operators are used as per intention. |
| C provide malloc() and calloc() functions for dynamic memory allocation. | C++ provides a new operator for this purpose. |
| C, allows Multiple Declaration of global variables. | In C++, Multiple Declaration of global variables are not allowed. |
| In C, Inheritance is not supported. | Inheritance is possible in C++ language. |
| Virtual Functions are present in C. | Virtual Function is not used in C++. |
| Contain 32 keywords. | Contains 52 keywords. |
| Polymorphism is not possible | Polymorphism is one of the most Important Features of OOPS. |
| C language offers GTK tool for GUI programming | C++ supports Qt tools for GUI programming |
