C language and C are two different programming languages which have some differences in syntax, features and usage. Following are some major differences between C language and C:
- Object-oriented programming: C++ is a language that supports object-oriented programming. It adds object-oriented features such as classes, objects, inheritance, and polymorphism to the C language. The C language is a procedural programming language that does not directly support object-oriented programming.
- Type checking: C++ has stricter type checking mechanisms, including features such as casts and runtime type information (RTTI). The type checking of the C language is relatively loose, allowing implicit type conversion.
- Standard library: The C++ standard library is richer than the C language standard library, including functions such as containers, algorithms, string processing, and input and output. The standard library of the C language is relatively small, mainly including basic input and output and string processing functions.
- Exception handling: C++ supports exception handling mechanism, you can use try-catch statement to catch and handle exceptions. The C language has no built-in exception handling mechanism, and errors are usually handled by returning error codes or using global variables.
- Memory management: C++ supports object-oriented memory management, including features such as constructors, destructors, and operator overloading. The C language requires manual memory management, including allocating and freeing memory.
- Compatibility: C is a superset of C language, that is, C can be compatible with C language code. C can directly call functions and libraries in C language, and code in C language can also be compiled and run in C.
In general, C adds object-oriented programming features to the C language, and has stricter type checking, a richer standard library, and a more advanced memory management mechanism. The choice of which language to use depends on the specific needs and project requirements. If you need object-oriented programming and more advanced features, you can choose C; if you only need basic programming functions and low overhead, you can choose C language.
