Kotlin Program to Display Prime Numbers Between Intervals Using Function: Below the program, we’ve created a function named check prime number() which takes a parameter num and returns a boolean value. If the number is prime, it returns true. If not, it returns false. Based on the return value, the number is printed on the screen inside the main() function.
