# Prime Number Program
# This program will allow the user to enter a number, then the program will
# determine if this number is a prime number or not. A prime number is the 
# number thats divided by itself and one. Any other numbers that divided to 
# more than one and itself then this numbers is not a prime numbers. for
# example 6 its divided by itself and one, pluse 2,3. so thats not a prime 
# number.
