Question 7

Which of the following statements is false?

Accepted Answer

A)  Names for structure types are often defined with typedef to create more readable type names. 
B)  The statement
Typedef Card* CardPtr;
Defines the new type name CardPtr as a synonym for type Card*. 
C)  Creating a new name with typedef does not create a new type; typedef simply creates a new type name that can then be used in the program as an alias for an existing type name. 
D)  C++11 added the keyword using as another mechanism for creating type aliases. The following declaration is equivalent to the typedef in part b):
Using Card* = CardPtr;
