C++ 十六进制与十进制互转

    int decimal = 100000;
    stringstream ss;
    //十进制转十六进制
    ss << "0X" << uppercase << setfill('0') << setw(4) << std::hex << decimal;
    cout<<"Convert to hex:"<<ss.str()<<endl;

    ss.clear();
    //十六进制转10进制
    ss.str("0x0F");
    ss>>hex>>decimal;
    cout<<"Convert to oct:"<<decimal<<endl;
