Member inaccessibility error

nuglyfe (21)
I need some help with accessing a member from a protected class.
The error is on line 17 of my .cpp file and its saying its inaccessible. But if it's inaccessible then why did an error message not generate for lines 11 and 12? The members are length and width in my rectangleType.h file

Your class seems to be quite popular. Also, a lot of those operator look abused.

About your error, compare

friend istream& operator>>(istream&, rectangleType&); //declaration
istream& operator>>(istream& isObject, rectangleType rec) //definition

Thanks for your eyes! I stared and stared but somehow how didn't see it.
