Program to determine whether or not a number is prime
Created on dd/mm/yy
@author: yourname
Algorithm:
1. input the number
Read(NUM)
2. determine that the NUM is prime or has divisors other than 1
2.1 determine if number is divisible by 2
If NUM = 2
Then NUM is a prime number
Else If NUM is even
Then NUM is not a prime number and halt
Else 2.11 determine if (NUM divisible by odd integers >= 3 and <= (square root of NUM))
For LOOP := 3 to sqrt(NUM) by 2
Do If (NUM mod LOOP) = 0
Then NUM is not a prime number and halt
3. if we get here, print a message that NUM is a prime number
Write(NUM,"is a prime number");
4. finished
Halt
