Outside the loop, we check if flag is True or False. If it is True, num is not a prime number. If it is False, num is a prime number. Note: We can improve our program by decreasing the range of numbers where we look for factors. In the above program, our search range is from...

2. Using Iteration We can use afor loopto check if the number has any divisors.Utilizing the property that one of the factors of a number must be less than or equal to its square root, we iterate only till the square root of the number. This way, we can improve the algorithm’s ef...
There are plenty of codes out in the public for using this method. Good luck! 14th Feb 2018, 2:58 PM Zeke Williams + 4 step 1: create a function which accepts a number and returns a boolean statement (true, false) step 2: create a for loop which increments the starting point until...
To check prime numbers, we declare a function isPrime() that will return 1, if number is prime and return 0 if number is not prime. Then, in main() function – we are using a loop with 0 to len-1 (total number of array elements) and calling isPrime() by passing array elements on...
