Answer 1

You can do it by this(which is used by Caffe: a fast open framework for deep learning):

// Disable the copy and assignment operator for a class.
#define DISABLE_COPY_AND_ASSIGN(classname) \
private:\
  classname(const classname&);\
  classname& operator=(const classname&)

Usage example:

class CNoCopyable{

    public:
        CNoCopyable(int i):m_d(i){}

    private:
        int m_d;
        // add this line(pass class name)
        DISABLE_COPY_AND_ASSIGN(CNoCopyable);

};
