Standard C ++ library style:

#include <sstream>
#include <string>

(...)

int number = 5;
std::stringstream ss;
ss << number;
std::string numberAsString(ss.str());

Or, if you are fortunate enough to use C ++ 11:

#include <string>

(...)

int number = 5;
std::string numberAsString = std::to_string(number);

You can use snprintf(char *str, size_t size, const char *format, ...)to get char [] and then use string(char*)get string. Of course, there are other ways.
