Operators
- Normal
|
|
There are several normal operators which return the result
defined for each:
expression1 + expression
The result of this is the sum of the two expressions.
expression1 - expression2
The result of this is the value of expression2
subtracted from expression1.
expression1 * expression2
The result of this is the value of expression1
multiplied by expression2.
expression1 / expression2
The result of this is the value of expression1
divided by expression2.
expression1 % expression2
The result of this is the value of the remainder after
dividing expression1 by expression2. Also
called the modulo operator.
expression1 & expression2
Returns a bitwise AND operation done on expression1
and expression2. The result is a value the same size
as the expressions with its bits modified using the
following rules: Both bits must be 1 (on) to result in 1
(on), otherwise the result is 0 (off).

expression1 | expression2
Returns a bitwise OR operation done on expression1
and expression2. The result is a value the same size
as the expressions with its bits modified using the
following rules: Both bits must be 0 (off) to result in 0
(off), otherwise the result is 1 (on).

expression1 ^ expression2
Returns a bitwise XOR operation done on expression1
and expression2. The result is a value the same size
as the expressions with its bits modified using the
following rules: If both bits are the same, then the result
is 0 (off), otherwise the result is 1 (on).

expression1 >> shift_value
Returns expression1 with its bits shifted to the
right by the shift_value. The leftmost bits are
replaced with zeros if the value is nonnegative or unsigned.
This result is the integer part of expression1
divided by 2 raised to the power of shift_value. If
expression1 is signed, then the result is
implementation specific.
expression1 << shift_value
Returns expression1 with its bits shifted to the left
by the shift_value. The rightmost bits are replaced
with zeros. This result is the value of expression1
multiplied by the value of 2 raised to the power of
shift_value. If expression1 is signed, then the
result is implementation specific.
