Logical Operators

Combine boolean expressions using logical AND, OR, and NOT.

Operators​

OperatorDescriptionExample
&&Logical ANDa && b
||Logical ORa || b
!Logical NOT!a

Examples​

a is true;
b is false;

Print(a && b);    // false
Print(a || b);    // true
Print(!a);        // false
Print(!b);        // true

Combining Conditions​

age is 25;
hasLicense is true;

if (age >= 18 && hasLicense) {
    Print("Can drive");
}

if (age < 13 || age > 65) {
    Print("Special pricing");
}

Short-Circuit Evaluation​

Logical operators use short-circuit evaluation:

  • && — if left side is false, right side is not evaluated
  • || — if left side is true, right side is not evaluated
