Kotlin - Operators and Expressions

You want to check if a user is logged in and has admin rights before allowing access. Which Kotlin condition correctly uses logical operators for this?

val loggedIn = true
val isAdmin = false
// Choose the correct if condition

Aif (loggedIn || isAdmin) { println("Access granted") }

Bif (!loggedIn || !isAdmin) { println("Access granted") }

Cif (!loggedIn && isAdmin) { println("Access granted") }

Dif (loggedIn && isAdmin) { println("Access granted") }

Step-by-Step Solution

Solution:

Step 1: Understand the requirement
Access is allowed only if user is logged in AND has admin rights.
Step 2: Analyze each condition
if (loggedIn && isAdmin) { println("Access granted") } uses && to require both loggedIn and isAdmin true. if (loggedIn || isAdmin) { println("Access granted") } allows access if either is true, which is wrong. The remaining options use negations or incorrect logic, which do not meet requirement.
Final Answer:
if (loggedIn && isAdmin) { println("Access granted") } -> Option D
Quick Check:
Use AND to require both conditions true [OK]

Quick Trick: Use && to require both true for access [OK]

Common Mistakes:

MISTAKES

Using || instead of &&
Negating conditions wrongly
Allowing access if only one is true
