Table mapping Strings to Strings

**johnmcg** · 09-03-2003

Hi,

I'm looking to create a table that will map strings to strings. The format will basically be:
---------------------------------------
| Name | Description |
----------------------------------------
| name1 | some info |
| name 2 | other info |

The only way I can think of doing this at the moment is by maintaining three arrays.
char name_array[Max_entries][Max_string_length];
char info_array[Max_entries][Max_string_length];
char** ptr_array[Max_entries][2];

so that when I add a record to name_array and info_array, I pass a pointer to the record I just added into ptr_Array. e.g.

ptr_array[x][1] = &name_array[i];
ptr_array[x][2] = &info_array[j];

Will this even work, or is there an easy way of doing it?

Any help appreciated.

If you used C++ then it would be extremely easy. You would just use a map<string,string> container. Is that an option or must it be vanilla C?

I'd probably use a struct to make things easier to read:

Code:

typedef struct Entry
{
  char *pName;
  char *pDescription;
} Entry;

Entry Table[100];

Table[0].pName = pAName;
Table[0].pDescription = pADescription;

But it's your choice...

Hi,

C++ isn't an option for legacy reasons. I reckon I'll use the struct suggested in a linked list.

Thanks for the help.

Have you considered using a hash table, or do you only have a few items to look up?
