Hi everyone,

There is a problem with Jes's logic here.  He wrote if (regNumber > 1 && 
regNumber < 3).

But 1 is not greater than 1, and 3 is not less than 3, so the only number that 
will be recognized here will be 2.

The if statement about 4 and 9 has the same problem.

What is meant, I feel sure, is 

if (regNumber >= 1 && regNumber <= 3)

That will pick up 1, 2 or 3.  Similar operators in the 4 and 9 statement will 
recognize all numbers from 4 to 9 inclusive.

I also think that there are difficulties with what is included in the while 
loop and what isn't, but haven't looked closely at that yet.

HTH.

  Hi Jim,
  The statement which talks about 4 and 9 tells the program, if there are 
between 4 and 9 registrants, the fee is 100 dollars.
  The whole thing goes like this:
  If a company enters  at least 1, up to 3 registrants, the fee is 150 dollars. 
If they enter 4 to 9 registrants, the fee is 100 dollars, and if it is ten or 
more people, it's 90 dollars.
  So, if I understand this correctly, Jim, if the first company entered 8 
people and the second company entered 10, the total fee would be 
  190 dollars. 100 dollars for the first 8 people, and then 90 dollars for the 
other ten.

    Hi,
    I can't figure this out. Maybe you need to have && in the statement that 
talks about > 4 & < 9. But what's going on if it is either 4 or 9?
