Please help! When I try to click "view profile," it flashes my profile for half a second, then it turns into this weird screen, which I will attach a screenshot of below. Did my account get deleted? If so, that would be really strange, because I provide very formal answers and I have given over 200 answers, and helped 4.9k people.

I contacted the help desk, but I just wanted to ask if anyone else was having the same issue. Could someone PLEASE try to click on my profile and tell me if you can see it, or if an error message pops up? I would really appreciate it. Thank you.

1)consider the following code snippet: #ifndef book_h#define book_hconst double max_cost = 1000.0; class book{public: book(); book(double new_cost); void set_cost(double new_cost); double get_cost() const; private: double cost; }; double calculate_terms(book bk); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_cost should be removed since header files should not contain constants.c)the definition of book should be removed since header files should not contain class definitions.d)the body of the calculate_terms function should be added to the header file.
