Objective:
- To become well-learned in the way of the while loop
Resources:
Directions:
- Prompt the user to enter a number, N
- Create a variable named isPrime and set it to True
- Use a loop that counts from 2 up to N/2
- If N is divisible by the loop counter, then set isPrime to False
- break out of the loop
- After the loop, check if isPrime is True,
- print out that it is a prime number,
- else, print out that it is not a prime number
Additional Challenges:
- Prompt the user for N
- Print out the first N prime numbers
