    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.

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