    File I/O: ios has not been declared?

    I don't know what's wrong. I've included "fstream" and "iostream", but the compiler said 'ios' has not been declared? Here's the faulty code:

    Code:
    	std::ofstream binary_file("settings.dat",ios::out|ios::binary);
    	binary_file.write(reinterpret_cast<char *>(&mData),sizeof(SettingData));
    	binary_file.close();
    What's wrong with it?
