Kotlin Program to Check Whether a Number is Positive or Negative

Kotlin Program to Check Whether a Number is Positive or Negative: This is done by using an if-else statement or a when expression in Kotlin. To check whether a number is positive or negative, you compare it with 0. If a number is greater than zero, it is a positive number. If a number is less than zero, it is a negative number.
