Variables
-23 % -5 = -3
23 % -5 = 3
-23 % 5 = -3
The result of the operation member1 % member2 is the remainder of dividing member1 by member2.
The value of member2 may not be zero. In the case member2 = 0, the error occurs, “Zero divide in
line 1”.
Besides the above-mentioned algebraic operations, logical (comparison) operations can be used in
expressions. The result of a logical operation is the numerical value 1, if the relation defined by the operation
is true, and 0 otherwise.
Logical Operations
Greater than ( > )
Less than ( < )
Greater than or equal ( >= )
Less than or equal ( 45 && 56 < 34
This example expresses the question: Is the number 23 greater than the number 45 and the number 56 less
than the number 34? Obviously, the answer will be - no, therefore the value of this expression is zero.
The expression !VAR_1 is the same as VAR_1 == 0
Logical operations are usually used for comparing the value of a variable against a constant or a value of
another variable. A shortcoming here is that only two values are possible as the result of evaluating a logical
expression - 0 or 1.
Another form of using logical operations is a conditional statement.
A conditional statement has the following structure:
condition ? value1 : value2
Example:
VAR_1 > 100 ? 1 : -1
If the value of VAR_1 is greater than 100, then the statement will yield 1, otherwise it yields -1.
One can use arbitrary expressions for the condition, value1 and value2.
VAR_1 ? 1 : -1
or, just the same thing,
VAR_1 != 0 ? 1 : -1
(VAR_1 != 0 && VAR_2 == 0) ? (VAR_3 + 1) : (VAR_4 -1)
