What does typedef struct mean in C++?

Basically struct is used to define a structure. But when we want to use it we have to use the struct keyword in C. If we use the typedef keyword, then a new name, we can use the struct by that name, without writing the struct keyword .28 Mar 2019

Not so in the C programming language. The use of typedef most often serves no purpose but to obfuscate the data structure usage . Since only { struct (6), enum (4), union (5) } number of keystrokes are used to declare a data type there is almost no use for the aliasing of the struct.

Struct is to create a data type. The typedef is to set a nickname for a data type .

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.
