Chapter 2. Types, Operators, and Expressions
2.9 Bitwise Operator
unsigned getbits(unsigned x, int p, int n)
return (x >> (p+1-n)) & ~(~0 << n);
Chapter 5. Pointers and Arrays
5.1 Pointers and Addresses
5.2 Pointers and Function Arguments
5.3 Pointers and Arrays
There is one difference between an array name and a pointer that must be kept in mind.
A pointer is a variable, so pa = a and pa++ are legal.
But an array name is not a variable; construction like a = pa and a++ are illegal.
5.4 Adress Arithmetic
The behavior is undefined for arithmetic or comparisons with pointers that do not point to members of the same array.
(There is one exception: the address of first element past the end of an array can be used in pointer arithmetic.)
5.5 Character Pointers and Functions
