How to check if a number is within given range?

Question

I have an age 24, and I want to return TRUE if 24 is within the range of 20 to 38, else FALSE.

Is this even possible?

Answer 1

if (age > 19 && age < 39) { return true; } else { return false; }

Answer 2

Very basic question. You know about if/else?

if (age >= 20 && age <= 38) {
    return true;
} else {
    return false;
}

Or

return (age >= 20 && age <= 38) ? true : false;

Or

return (age >= 20 && age <= 38);

Answer 3

return (age >= 20 && age <= 38);
