WebApr 12, 2024 · Inside the for loop, we check if the number is divisible by any number in the given range (2...num/2). If num is divisible, flag is set to true and we break out of the loop. This determines num is not a prime number. If num isn't divisible by any number, flag is false and num is a prime number. WebSince 0 and 1 are not prime numbers, we first check if the input number is one of those numbers or not. If the input number is either 0 or 1, then the value of is_prime is set to false. Else, the initial value of is_prime is left unchanged. Then, the for loop is executed, which checks whether the number entered by the user is perfectly ...
