I am stuck at a regEx problem that says "Make a regex that matches a string of 10 characters that always iterate between uppercase and lowercase letters."
The question is from a online quiz kind of thing, and when you input your response it tells you whether it is right or wrong.
I have tried a bunch of options but none of them work, as the question is a bit blurry for me.
([a-z][A-Z])5
([a-z][A-Z])5|([A-Z][a-z])5
According to me, I believe that the question simply wants us to match strings like AaAaAaAaAa or aAaAaAaAaA

I'm not sure about the code you need to incorporate this regexp in and id it suppose to get exactly 10 characters, but you are probably in the right direction. I think you can use this:
b(?:[a-z][A-Z]|[A-Z][a-z])5b

Your current pattern matches a repetition of 5 times 2 characters but has no specific boundaries. What you might do is use word boundaries b([A-Z][a-z])5b
Another option could be to use anchors to assert the start and the end of the string and use a positive lookahead to assert the length of the string to 10:
^(?=.10$)[A-Z]?(?:[a-z][A-Z])+[a-z]?$
Explanation
^Start of the string(?=[a-zA-Z]10$)Assert lenght of 10 characters a-z[A-Z]?Match optional uppercase char(?:[a-z][A-Z])+Match 1+ times a lowercase char followed by an uppercase char[a-z]?Match optional lowercase char$End of string
