What exactly is the error message? The ones I'm getting are pretty straight forward.

Your "login" is still not returning a bool. You say it should, but I don't see a return anywhere in it. That is one of the more subtle problems.

The other problems are big as trucks, and your compiler should tell you the problem in clear everyday English.

EDIT:
"In function 'int main()':" Means there is a problem in 'int main()'. Then, there's supposed to be the actual problem. Remember that an error message can span several lines...
