s_word == "aa", t_word == "TO"
then for s_word: firstupper is false, uppercase is false, sizeone is false
if(!uppercase || (sizeone && uppercase))
{
result = t_word;
result[0] = towlower(result[0]);
//result = StringUtils::tolower(t_word);
}
else
{
result = StringUtils::toupper(t_word);
}
if(firstupper)
{
result[0] = towupper(result[0]);
}
gives us "tO" (first test passes). If we change the first test to
if(!uppercase || (sizeone && uppercase))
{
result = t_word;
//result[0] = towlower(result[0]);
result = StringUtils::tolower(t_word);
}
we get the expected "to". Does anyone know why we would want to only
lowercase the first character?
On a related note, why is sizeone&&uppercase treated as if it were
lowercase? Isn't it safer to simply ignore sizeone words passed to
modify-case? E.g.
if(!sizeone){
if(!uppercase) { tolower }
else { toupper }
if(firstupper) { toupper [0] }
}
