Is typedef ever required in C?

Question

Typedef is very useful for portable names, tag names (typedef struct foo Foo;) and keeping complicated (function) declarations readable (typedef int (*cmpfunc

Answer 1

Without typedef, you have to use the keyword struct everytime if you use a struct in declarations. With typedef, you can omit this.

struct Person
{
  char * name;
};

struct Person p; /* need this here*/

typedef struct _Person
{
  char * name;
} Person;

Person p; /* with typedef I can omit struct keyword here */
