Chapter: 2 / Q: e.g2.3.2.10
The type void* is a special pointer type that can hold the address of any object. Like any other pointer, a void* pointer holds an address, but the type of the object at that address is unknown
Chapter: 2 / Q: e.g2.3.3.1
As we’ve seen, a variable definition consists of a base type and a list of declarators. Each declarator can relate its variable to the base type differently from the other declarators in the same definition. Thus, a single definition might define variables of different types
Chapter: 2 / Q: e.g2.3.3.2
Part of the problem arises because we can put whitespace between the type modifier and the name being declared
Chapter: 2 / Q: e.g2.3.3.3
The * modifies the type of p. It says nothing about any other objects that might be declared in the same statement
Chapter: 2 / Q: e.g2.3.3.4
There are two common styles used to define multiple variables with pointer or reference type. The first places the type modifier adjacent to the identifier
Chapter: 2 / Q: e.g2.3.3.5
The second places the type modifier with the type but defines only one variable per statement
Chapter: 2 / Q: e.g2.3.3.6
We indicate each pointer level by its own *. That is, we write ** for a pointer to a pointer, *** for a pointer to a pointer to a pointer, and so on
Chapter: 2 / Q: e.g2.3.3.7
To access the underlying object, we must dereference the original pointer twice
Chapter: 2 / Q: e.g2.3.3.8
A reference is not an object. Hence, we may not have a pointer to a reference. However, because a pointer is an object, we can define a reference to a pointer
Chapter: 2 / Q: e.g2.4.1
We can make a variable unchangeable by defining the variable’s type as const
