I need to write a program that accepts a number and finds an integer whose square is less than the number entered using only do loop and no other functions. I can use only one input and one output variable.
This is what I have and it's wrong:
cls
max=max-1
input "please enter a number"; max
do until max2<max
max2=(max*max)
loop
print max2

Can you help?

The way you worded it, given the number is positive then 0 is a correct answer for any number. That's not too bad =) Your code wont work. I think you need to write what you want to do on paper and then do it in chronological order. This would do just fine:
Note the >=.
