Array of Strings??

[Simon Mansfield]

Hey everyone, I have created a struct called employee, as follows:

struct employee {
int pid;
char name[3];
char job[40];
int hourlyRate;
struct employee *next;
}

Which will become a linked list (obviously!).. Now I want to add one more
field, a "appointment" field... Now the idea is that when a customer wants
to book the particular employee they put their name in the corresponding
array slot. ( eg. Ms. Saunders wants 10 am should be appointments [10] =
"Ms. Saunders" ) however I have no idea of how to create an array of
strings.. or even if it's possible.. Bit of a noob, i know! (But u gotta
start at some point!!)

Any other suggestions will be welcomed and the entired project can be sent
via e-mail upon request if you wish to have a closer look..

An array of strings is created the same way an array of anything else is
created: you start with your BASE element and extend an array.

For example, a BASE element, and an array of 5 integers:

int ele;
int group[5];

Here ele is the name of a BASE, and group is the name of an array of
elements.

Character strings are no different. Your BASE element is declared as:
char *string;

I had this problem too.

an array of strings:

char **array;
int nstr; /* Number of strings */
int wstr; /* String width */

nstr = 8;
/* Allocate memory for the array of pointers
* (which point to the strings) */
array = (char **) calloc (nstr, sizeof (char *));

/* Memory is statically allocated for string */
array[0] = "text";

/* Memory is dynamically allocated for string */
wstr = 80;
array[2] = (char *) calloc (wstr, sizeof (char));

/* Reads a string from stdin */
fgetc (array[2], wstr, stdin);

How about

struct employee {
int pid;
char name[3];
char job[40];
int hourlyRate;

char appointment[12][40]; /*12 appointments with room for 39 characters
in each string*/

struct employee *next;
}

Thanks a lot everyone... I think i'm going to try to attempt something along
the lines of what code_wrong suggested, since it seems to be the simplest
solution and I am trying to keep things simple

Thanks all.. I'll let you know if I have any further problems.
