Kotlin - Control Flow as Expressions
You want to print a message based on temperature using when without argument. Which code correctly prints "Cold" if temp < 10, "Warm" if between 10 and 25, and "Hot" otherwise?
when {
temp < 10 -> println("Cold")
temp in 10..25 -> println("Warm")
else -> println("Hot")
} uses correct when without argument syntax with -> and else branch.
Step 2: Verify condition coverage
when {
temp < 10 -> println("Cold")
temp in 10..25 -> println("Warm")
else -> println("Hot")
} covers temp < 10, temp in 10..25, else for others correctly.
Final Answer:
when {
temp < 10 -> println("Cold")
temp in 10..25 -> println("Warm")
else -> println("Hot")
} -> Option A
Quick Check:
Use when without argument with proper arrows and else [OK]
Quick Trick:Use range with in and else for full coverage [OK]
Common Mistakes:
MISTAKES
Using parentheses with when without argument
Using colon instead of arrow
Incorrect condition ranges
