Ruby Array Stack Class


my assignment is to implement a stack class (based on Array) using push, pop, length and empty.

Also, to provide example test code which makes use of the stack.  
Have I satisfied this?  At line 21 would be the example code?  or is this part of my stack?

Thanks for looking, my professor expects us to pick up Ruby in one week and won't answer questions over the Holiday.

Seems to work fine for me; yes, line 21 on is your test code.

It's always a good thing to test some of the boundary conditions, like what happens when you try to pop from an empty stack... I added this to your test code at the end, when the stack was empty.

If you can think of other error or boundary conditions, you can add those to your test suite as well.


test = stack.pop
puts "Result from empty stack: " +( test.nil? ? "nil" : test)
puts stack.length
