Try:
{
#define TEMPSTRSIZE 64
char TempStr[TEMPSTRSIZE];
UInt16 n;
n = 28;
StrIToA(TempStr, n);
StrNCat(TempStr, " days", sizeof(TempStr));
// For 'You have 28 days remaining.' you can use
StrNCopy(TempStr, "You have ", sizeof(TempStr));
StrIToA(&TempStr[StrLen(TempStr)], n); // not overrun-safe
StrNCat(TempStr, " days remaining.", sizeof(TempStr));
// The '&TempStr[StrLen(TempStr)]' isn't very efficient but
// is fine for building up strings on the fly.
// For commercial apps you should also consider storing
// your strings as resources so that translation to another
// langauge is easier. This takes a little time to set up
// but saves a lot of pain later on.
// alternatively you can use the TEMPSTRSIZE constant.
// In theory they're the same because sizeof() should
// be resolvable at compile time but I've never checked
// to see if CodeWarrior does this.
StrNCopy(TempStr, "You have ", TEMPSTRSIZE);
StrIToA(&TempStr[StrLen(TempStr)], n);
StrNCat(TempStr, " days", TEMPSTRSIZE);
}
I've used the StrN~ operators rather than the Str~ because they
protect against buffer over-runs which can Produce some particularly
nasty bugs (nasty = intermittent crashes and corruption side-effects)
Of course this might lead to a discussion on coding style :-)
