Standard C++ library style:

#include <sstream>
#include <string>

(...)

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

Or if you're lucky enough to be using C++11:

#include <string>

(...)

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

You could use snprintf(char *str, size_t size, const char *format, ...) to get a char[], then use string(char*) get string. Of course，there're other ways.
