The difference between C language and C
Introduction
C language is a programming language with a long history, known for its efficiency, portability and Known for low-level memory operations. C is an object-oriented programming language developed based on the C language and introduces concepts such as classes, inheritance, and polymorphism.
Main differences
1. Object-oriented programming
- C is an object-oriented language that supports Classes, objects, and inheritance, and C is a procedural language.
- In C, data and methods are encapsulated in classes, while in C they exist in the form of global variables and functions.
2. Data abstraction
- #Data abstraction in C allows data and data manipulation methods to be hidden in classes, making the code more accessible. Maintainability and security.
- There is no concept of data abstraction in C, all data and operations are public.
3. Memory management
- C implements automatic memory management through the destructor. When the object goes out of scope, it will be automatically released Memory.
- In C, memory management is the manual responsibility of the programmer, requiring the use of functions such as malloc and free.
4. Templates
- C supports generic programming, allowing the development of reusable code.
- C Templates are not supported.
5. Exception handling
- C provides an exception handling mechanism to handle runtime errors.
- There is no built-in exception handling mechanism in C.
Other Differences
- C introduces references, pointer member functions, and operator overloading, while C does not have these features.
- C follows the C standard, and C follows the C standard.
- Compilers in C are generally more complex than C compilers.
Summary
The C language is an efficient, procedural programming language, while C is an object-oriented language that provides advanced features such as data abstraction , memory management, templates and exception handling.
