this depends on if you know the size of the array before:
1. you know the size:
    char *aszStrings[iNumberOfStrings];
    allocate each with:
    char *aszStrings[i] = [your line...];
2. if you dont know the number you might have to use a linked list:
    typedef struct _node_structStringList{
    char *szString;
    _node_structStringList *next;
    }SNodeStringList;

    and so on...

maybe changing to c++ is the better idea... you can use string classes which
have been already written and tested a thousand times.
