عملگرهای منطقی

 

3 نوع عملگر منطقی وجود دارد:

عملگر	معنی	مثال
&&	AND منطقی	(x >= 1) && (x <= 100)
||	OR منطقی	(x < 1) || (x > 100)
!	NOT منطقی	(x == 8)!

 

مثال:

 

// Return true if x is between 0 and 100 (inclusive)
(x >= 0) && (x <= 100)  // AND (&&)
// Incorrect to use 0 <= x <= 100

// Return true if x is outside 0 and 100 (inclusive)
(x < 0) || (x > 100)       // OR (||)
!((x >= 0) && (x <= 100))  // NOT (!), AND (&&)

// Return true if "year" is a leap year
// A year is a leap year if it is divisible by 4 but not by 100, or it is divisible by 400.
((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)
