snprintf vs std::stringstream

问题:

I am working on removing SECURITY CODING violation in my product. My code has lot of sprintf, coverity tool is suggesting me to use snprintf, But C++ also has std::stringstream. Will it be a good idea to use std::stringstream in place of snprintf

回答1:

std::stringstream is typesafe, use operator <<, use internal buffer, part of C++, not so fast as sprintf.
sprintf is not typesafe, not use c++ operators, use external buffer, use elipsis, which can works only with POD types, inherited from C, fast.
