typedef and using

• C++ now provides two ways to "nickname" a type.
  • typedef oldType newType;
  • using newType = oldtype;
• The first is old and inherited from C
• The second is part of C++11
  • So this is not included in the book.
  • But this is superior.
    • Stroustrup explains why here.
• You should use the second.
  • Here is a reference.
  • Or just look at the code I have provided.
• When I create new types,
  • I use camelcase like a function name.
  • But I end with a T
  • using NumberT = int;
• Look at nicname.cpp
