Thread: what does this typedef line..

first i create this structure :

Code:

struct album { 
  char *name; 
  char *artist; 
  int numTracks; 
}

if i want my variables not to be global
i can write this inside main:

struct album CD1, CD2, CD3;

or
"
typedef struct album Album;

... then inside main:

Album CD1, CD2, CD3; "

i cant understand this last part regarding where to write the typedef line

and what is the role of type of typedef?

typedef creates an alias for a type. so you can do

struct album CD1, CD2, CD3;

or you can do

Album CD1, CD2, CD3;

Both mean the same thing.

thanks

first put a ; after the structure ends and after that function declaration and then typedef the structure then write main
