Question #3: Write a program that asks the user to enter an integer number and checks whether the number is prime or not. Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37...) is a natural number greater than I that has no positive divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not. Question #4: Re-write the program of Question #3 using data files. The input data numbers.txt contains (positive) integer numbers. Each time the program reads a number, check whether it is a prime and stores the result in the output file Results.txt. 373 373 is Prime!! 11 is Prime!! 11 2552 is NOT prime!! 5 is Prime!! 3561 is NOT prime!!

Question #3:
Write a program that asks the user to enter an integer number and checks whether the number is prime or not.
Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 . .) is a natural number greater than 1 that has no positive
divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If
remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not.
Question #4:
Re-write the program of Question #3 using data files. The input data numbers.txt contains (positive) integer
numbers. Each time the program reads a number, check whether it is a prime and stores the result in the
output file Results.txt.
