Article Introduction：The usage of typedef is: 1. Typedef basic data types take "aliases". All data types in C language can use typedef to redefine the type name; 2. Typedef takes "aliases" for custom data types. Customized data types include : Structure struct name{ };, Union unit name { };, Enum { }; 3. Typedef takes "alias" for array; 4. Typedef takes "alias" for pointer.

Article Introduction：The difference between typedef struct and struct: typedef struct creates an alias of a structure type, while struct defines a new structure type. The alias created by typedef struct can be used after it is declared, while the structure defined by struct can be used after it is defined. Neither typedef struct nor struct creates additional storage space.

Article Introduction：typedef is used in C language to create a new data type alias to improve code readability, maintainability and portability. Its syntax is: typedef <existing data type> <new data type name>. For example, typedef int my_int; creates an alias named my_int, which is actually the int data type.

Article Introduction：The usage of typedef in C language includes defining basic type aliases, defining structure aliases, defining pointer type aliases, defining enumeration type aliases, defining array type aliases, etc. Detailed introduction: 1. Define basic type aliases, typedef can be used to define aliases of basic types, making the code more readable; 2. Define structure aliases, typedef can also be used to define aliases for structures, making the structure type more concise; 3. Define pointer type aliases. Typedef can also be used to define pointer type aliases to make pointer types more readable, etc.

Article Introduction：The typedef struct syntax is used to create a new structure type alias. The syntax is: typedef struct struct_name {struct member declaration} new_type_name; it allows the use of aliases to replace the structure name, improves readability and maintainability, and avoids name conflicts. .

Article Introduction：The difference between typedef and define lies in type checking, scope, readability, error handling, memory usage, etc. Detailed introduction: 1. Type checking, the type alias defined by typedef is a real type, and type checking will be performed, while the macro defined by define is just a simple text replacement, and type checking will not be performed; 2. Scope, the type alias defined by typedef The scope of is local and only valid within the current scope, while the macro defined by define is global and can be used anywhere; 3. Readability, etc.
