The stunt on this subject is too big to be really written, enough to write a book.I am an experienced person, combined with their own experience and exchanges, I hope the new people can less detours.Each person's situation is different, my

To tell the truth, a lot of people have done a long time C + +, but also use a lot of Ides, but for the implementation of the underlying generation of a blank, this is undoubtedly a sad, you can imagine the big company interview just be asked this

The inheritance protection level of the 1.c++ is best shown to be written out. (Note: The default inheritance for class is Private,struct's default inheritance is public).Cases:Class base{/**/};struct d1:base{/**/}; Default is PublicClass d2:base{/**

The combination will be grouped together. Programming is to use existing classes of objects to generate new classes.  The table is made up of planks and nails, and the lamp uses a lamp holder, a lamp, a wire, a joint, etc. We find that many things
