Where do I get documentation on all this? When I search the msdn library
that comes with Visual Studio, I find only those functions that work with
char str[] types. What function do I need to use to get the length of a
value of type std::string?

Now I can't use the _itoa_s function because it requires a char type.
What function could I use to convert an integer value to a std::string
value. I tried to use a cast but it would not work.

You may use code like this:

<code>

#include <string> // string
#include <sstream> // ostringstream

// Convert int to STL string
std::string ToString( int n )
{
   std::ostringstream os;
   os << n;
   return os.str();
}

</code>

and use like this:

std::string s = ToString( 10 );

Or you may use an implementation based on C sprintf:

<code>

// Convert int to STL string
std::string ToString( int n )
{
   char buf[ 100 ]; // Big enough buffer
   sprintf( buf, "%d", n );
   return std::string( buf );
}

</code>
