Validating each value using a while loop

I am writing a script that would validate a statement. The tasl is to promt the user for the values specified below. For each value entered by the user, use a while loop to validate each value according to below. The statement I am trying to validate is "Number of Subintervals" and the value has to be greater than 1. N>1 where N=subintervals.

This is what I got and it does not work.

N=input('enter a number of subintervals greather than one')
while N>1
    if N<1
        disp('Please enter a number greater than 1')
    end
end

If there is anyway you could help that would be great as I am new to coding.

What should happen when

• user enters 0
• user enters 2

???

If the user enters 2 the while-loop of your code will loop forever.

[Michael Doherty]

If the user enters a number less than one, they should be prompted with a statement to enter a number greater than one. If the user enters a number greater than one, it should leave the loop to continue on to another statement validation.

I think your while loop needs to have the input() within it

While the user hasn't given a valid number

Ask for a number

if the number is good, leave the loop

else offer a suggestion

end while
