C++ LANGUAGE TYPEDEF KEYWORD

The typedef Keyword 


There is an easier way to define structs or you could "alias" 
types you create. For example: 


typedef struct 
{ 
   char  title[50]; 
   char  author[50]; 
   char  subject[100]; 
   int   book_id; 
}Books; 

Now, you can use Books directly to define variables of Books type 
without using struct keyword. Following is the example: 
Books Book1, Book2; 
You can use typedef keyword for non-structs as well as follows: 
typedef long int *pint32; 
  
pint32 x, y, z; 
x, y and z are all pointers to long ints.
