Kernighan & Ritchie, "The C Programming Language", 2nd edition, section
5.3, page 99:

"Since the name of an array is a synonym for the location of the initial
element, the assignment pa=&a[0] can also be written as pa=a"

The reference part, section A7.1, goes into more detail. "If the type of
an expression or subexpression is array of T, for some type T, then the
value of the expression is a pointer to the first object in the array,
and the type of the expression is altered to pointer to T." It then
lists a few exceptions, including the & operator is used (hence, a and
&a returns the exact same thing if a is an array).
