3.9 Consider an application App that takes two inputs name and age where name is a non-empty string containing at most 20 alphabetic characters and age is an integer that must satisfy the constraint 0 age 120. App is required to display an error message if the input value provided for age is out of range. It truncates any name that is more than 20 characters in length and generates an error message if an empty string is supplied for name. Partition the input domain using (a) uni-dimensional partitioning and (b) multidimensional partitioning. Construct two sets of test data for App using the equivalence classes derived in (a) and in (b).

I realize the amount of info needed for the first question I had was just way too much, so I'll work on it myself. I'll just leave this one, if it's not enough info please specify what you might need. Thank you
