For beginners? oh, good.
i have a problem with getting the values from a short int type var into a std::string string.
i tried the following(+ with static_cast<char>):
In STL there is no coercion support between strings and numbers. Use the std::stringstream:

#include <sstream>#include <string>std::stringstream s;s << getFPS();// To get the std::string call str() on the std::stringstreamstd::cout << s.str();Greetz,

operator+= for std::string only accepts characters, C-style strings, or std::strings. If you want to convert an integer to a string, you can use std::stringstream:
Then you can use result. You can also use stringstreams to convert other other way, if you'd like.
Later on in your career, look into boost::lexical_cast, which provides the same functionality but in a cleaner package. You may not quite be ready for Boost, yet. It can be daunting...

thank you, and i'll look into boost, since i've heard so much about it already.
