    Question Table mapping Strings to Strings

    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 used to be an adventurer like you... then I took an arrow to the knee.

    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...
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    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?
