Question

typedef struct
{
int id;
char*  first;
char* last;
}* person;

person* people;

Hi.
How can I use this above, all set globally, to fill people with different “person”s? I am having issues wrapping my head regarding the typedef struct pointer.
I am aware pointers are like arrays, but I’m having issues getting this all together…

I would like to keep the above code as is as well.

Edit 1: char first should be char* first.

Answer 1

You could simply create an array of structures of type person using something like following:

people = malloc (num_person * sizeof(person));
for (i = 0; i < num_person; i++) {
     people[i]->first = malloc (size * sizeof(char));
     people[i]->last = malloc (size * sizeof(char));
}

Following this, you could fill up each people struct with different parameters.
