Q:

Point out the error, ifany, in the followingb code? 

Additional Details

typedef struct

{

     int data;

     NODEPTR link;

} *NODEPTR;

 

 

Answer:



A typedef defines a new name for a type, and in simpler cases like the one shown below you can define a new structure type and a typedef for it at the same time.


typedef struct


{


    char name[20];


    int age;


} emp;


However, in the structure defined in this question, there is an error because a typedef declaration cannot be used until it is defined. In the given code fragment the typedef declaration is not yet defined at he point where the link field is declared.
