each line will be saved in a vector array that will be passed to the following function.

void WuManber::Initialize( const vector<const char *> &patterns, 
                  bool bCaseSensitive, bool bIncludeSpecialCharacters, bool       bIncludeExtendedAscii )

Answer 1

use stringstream

#include <sstream>
using namespace std;

void foo()
{
    istringstream ss("30");
    int i;
    ss >> hex >> i;
}
