2.3.3. Understanding Compound Type Declarations

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:

// i is an int; p is a pointer to int; r is a reference to intint i = 1024, *p = &i, &r = i;

Warning

Many programmers are confused by the interaction between the base type and the type modification that may be part of a declarator. ...
