For that line to work you need to use a compiler that at least supports the C++11 standard. If you have such a compiler you will get another error message telling you that there is no bookType constructor that match the arguments that you tried to pass.

Interestingly enough, there are several examples of such constructors in this thread:

I think I am using very old compilers.
I will google the new ones.

Thank you all
