Re: Structures or Array Notation for many possible strings of finite length?

"nospam" <nospam@xxxxxxxxxx> wrote in message
I have an application that processes 30 kinds of strings of that fit
in an array.

By processing, I mean
-check the value of certain characters or substrings to be
within contant bounds or a member of a list
-check the value of certain characters or substrings to be
within bounds defined by other characters or substrings
-call a series of functions based on value of certain
substrings.

Each kind of string has a different length, but it fits within an
array of 128 char's


Would you do the processing with array notation (using #defines for
the array indices) in order to write the clearest code , or would you
setup a union of 30 structs (one struct for each kind of sentence) to
write clearest code?

A union of 30 types is pretty unwieldy, and generally unions are a bad idea.

The string itself fits in an array, then presumably it needs to be tagged
with a type identifier. So I'd declare

typedef struct
{
char text[128];
int type;
} SENTENCE;

then
#define SIMPLEVERB 1
#define COMPOUNDSUBJUNCTIVE 2

or whatever you need.

Some code can presumable work on all sentences, some only on a subset. So
examine the type meber and process as appropriate.
