C Expressions for Assembly Language Programmers
12-3 Basic Information About C Expressions
-
Increment and decrement operators
++ increment – – decrement
These unary operators can precede or follow a symbol. When the operator
precedes a symbol, the symbol value is incremented/decremented before
it is used in the expression; when the operator follows a symbol, the sym-
bol value is incremented/decremented after it is used in the expression.
Because these operators affect the symbol’s final value, they have side
effects.
-
Bitwise operators
& bitwise AND | bitwise OR
^ bitwise exclusive-OR << left shift
>> right shift ~ 1s complement (unary)
-
Assignment operators
= assignment + = assignment with addition
– = assignment with subtrac-
tion / = assignment with division
% = assignment with modulo & = assignment with bitwise
AND
^ = assignment with bitwise
XOR | = assignment with bitwise OR
<< = assignment with left shift >> = assignment with right shift
* = assignment with multiplica-
tion
These operators support a shorthand version of the familiar binary expres-
sions; for example, X = X + Y can be written in C as X += Y. Because these
operators affect a symbol’s final value, they have side effects.
