The flow chart as given in the question.

State what numbers will be printed from this flow chart if \(X\) is read as (a) \(6\), (b) \(9\) and (c) \(20\). What is the relation between \(X\) and the numbers printed?

This flow chart is intended for use with \(X\) being a positive integer. What would happen if \(X\) were read to be \(2.4\)? Suggest a simple change to the second decision box to avoid this problem.
