How about if I add all of the assumed bits? Copy the code below exactly
as written and paste it in. See if it compiles.

=== begin code ===
#include <limits>
#include <sstream>
#include <stdexcept>
#include <string>

int extractNumber( const std::string& str )
{
using namespace std;
int result = 0;
stringstream ss( str );
while ( !( ss >> result ) ) {
if ( !ss.eof() ) {
ss.clear();
ss.ignore( numeric_limits<streamsize>::max(), ' ' );
}
else {
throw runtime_error( "no number" );
}
}
return result;
}

=== end code ===
