:(

Don't bother making main take arguments if you aren't going to use them.

Ew, strcpy and memory allocation...just use an std::vector, then just .find() and .substr() to get the individual words...

if(Pig_Latin == ""){

You can replace that with: if(Pig_Latin.empty())

For your "KillCaps" you could use:
std::transform(str.begin(), str.end(), &tolower);

For your "Killpunct" you could use:

class add_char {
    std::string operator ()(std::string str, char chr) {
        if(isalpha(curChar) || isspace(curChar)) {
            str += chr;
        }
        return str;
    }
}

new_str = std::accumulate(str.begin(), str.end(), string(""), add_char);

^I think this works, haven't tested it though
