Pointer to Structure

• -> operator

e.g. struct person x;

struct person *ptr;

ptr = &x;

strcpy((*ptr).name,”Chan Tai Man”); or

strcpy(ptr->name,”Chan Tai Man”);

i.e. (*ptr).member <=> ptr-> member

• Like passing array, sometime pointer to record is passed to a function in order to save memory

e.g. in lab 11stuInfo() can be rewritten as

void stuInfo(struct grades *);

and change the first input statement to

gets(students->name);
