Kotlin - Functions

Which of the following is the correct way to declare a simple function named greet in Kotlin that takes no parameters and returns no value?

Afunction greet() { println("Hello") }

Bfun greet() { println("Hello") }

Cdef greet() { println("Hello") }

Dfun greet { println("Hello") }

Step-by-Step Solution

Solution:

Step 1: Identify the correct keyword for function declaration
Kotlin uses the keyword fun to declare functions. Options using function or def are incorrect.
Step 2: Check the function syntax for parameters and braces
The function must have parentheses even if there are no parameters, so fun greet { println("Hello") } is incorrect because it misses parentheses.
Final Answer:
fun greet() { println("Hello") } -> Option B
Quick Check:
fun + name + () + body = B [OK]

Quick Trick: Remember: Kotlin functions start with 'fun' and need parentheses [OK]
