6.16进制字符串转10进制字符串

string Hex2String10(string strSrc)
    {
            int iNumber = strSrc.size();
            int iValue = 0;

            for(int i=0;i<iNumber;i++)

                iValue += iTemp*pow(16,(iNumber-i-1));
            }

            stringstream stream;
            stream << iValue;

            return stream.str();
