What is the meaning of typedef struct in C?

The C language contains the typedef keyword to allow users to provide alternative names for the primitive (e.g.,​ int) and user-defined​ (e.g struct) data types . Remember, this keyword adds a new name for some existing data type but does not create a new type.

The typedef keyword allows the programmer to create new names for types such as int or, more commonly in C++, templated types–it literally stands for “type definition”. Typedefs can be used both to provide more clarity to your code and to make it easier to make changes to the underlying data types that you use .

Difference between typedef and #define: typedef is limited to giving symbolic names to types only, whereas #define can be used to define an alias for values as well , e.g., you can define 1 as ONE, 3.14 as PI, etc.25 Haz 2020
