Boost libraries provide a better way to convert numbers into strings or vice versa. You must install the Boost libraries on your computer to make this work (click here for more info on Boost libraries ).

#include <boost/lexical_cast.hpp>//  Number to Unicode stringstd::wstring wcs = 	boost::lexical_cast(1234);//  Number to char stringstd::string s = 	boost::lexical_cast(1234);//  Unicode string to numberdouble d = boost::lexical_cast(wcs);//  char string to numberdouble d = boost::lexical_cast

Because these conversions throw exceptions if your conversions are impossible, they're a lot safer than using sprintf() or atoi().
