Can someone help me with this ruby code.

Question

It keeps on telling me that "undefined method 'upcase' for ["med", "sof"]: Array" But rather accept reverse order.

arr = ["med", "sof"]
test = arr.upcase
print test

Answer 1

@merkrafter has the right code, keep in mind that if you want to upper case a specific value you need to specify the array value or if you want the whole array to be upper cased then you might need to iterate through each values.

Answer 2

There is no upcase method defined for arrays. Try to use it for every entry of your array like:
arr = [...]
for x in arr
x.upcase!
end
print arr
