The difference between c++ and c language

Difference: 1. C supports OOP concepts such as classes, inheritance, polymorphism, etc., while the C language itself does not directly support OOP; 2. Compared with the C language, C introduces more new features. For example, function overloading, operator overloading, templates, exception handling, etc.; 3. The C standard library provides a wealth of functions, while the C language standard library is relatively small and has limited functions; 4. C is compatible with the C language and can be directly Calling functions and libraries of C language, but C language cannot; 5. C introduces the concept of namespace, but C language does not have this concept.

There are several major differences between C and the C language:

1. Object-oriented Programming (OOP) support: C is an object-oriented programming language that supports OOP concepts such as classes, inheritance, and polymorphism. Although the C language can implement object-oriented programming style, it does not directly support OOP itself.

2. New features: Compared with C language, C has introduced more new features, such as function overloading, operator overloading, templates, exception handling, etc. These features make C more flexible and powerful.

3. Standard library: The C standard library provides a wealth of functions, including containers, algorithms, input and output streams, etc., while the standard library of the C language is relatively small and has limited functions.

4. Compilation method: The C compiler generally converts the C code into C code, and then the C compiler compiles it. This means that C is compatible with the C language and can directly call functions and libraries of the C language.

5. Namespace (Namespace): C introduces the concept of namespace to avoid naming conflicts, but C language does not have this concept.

In general, C is developed on the basis of C language. It is more powerful and flexible than C language in terms of syntax, functions and application fields.
