Introduction to typedef in C typedef is a predefined keyword in C language. This typedef keyword tells the C compiler that “please assign a user given keyword to the already existing type”. It Means typedef gives an alternative user-friendly keyword for existing C language data types like unsigned int, long, int, char, float, etc.

Typedef¶ The typedef keyword allows us to rename a data type to a name that has more meaning to our program. The only purpose of typedef is increased program clarity.

C语言允许用户使用 typedef 关键字来定义自己习惯的数据类型名称，来替代系统默认的基本类型名称、数组类型名称、指针类型名称与用户自定义的结构型名称、共用型名称、枚举型名称

typedef can be used to rename any data type including enum and struct definitions, which we will study shortly. The typedef declaration provides a way to declare an identifier as a type alias, to be used to replace a possibly complex type name The keyword typedef is used in a declaration, in the grammatical position of a storage-class specifier, except that it does not affect storage or linkage: typedef names for structs could be in conflict with other identifiers of other parts of the program.

Visit Our Website for Classroom typedef struct type24 { char x[3]; } type24; In C++ you don't have to go to the trouble of using the typedef when declaring the struct type (in C this is done to avoid having to type struct all over the place). typedef in C is an important keyword that is used to define a new name for existing types, it does not introduce a new type. The typedef is the compiler directive mainly use with user-defined data types (structure, union or enum) to reduce their complexity and increase the code readability and portability.
