the itoa()method will convert a int to a string (or rather, a char array). Likewise, atoi will convert a string to an int.

itoa is not portable. You can use sprintf or an ostringstream,

For example, the declaration for std::ostringstream can be added into your program by including . std::ostringstream is a typedef for a specialization of std::basic_ostringstream (which has a member function called str()). So you can create an ostringstream object, use an inserter on it with the number to output and then get a string back with the output.
