Charlie, a beginner student of cryptography tries to design an original encryption scheme (warning: do not try this at home). One step is mixing two streams of hexadecimal digits (0 to 9, A to F). The digits of each stream must appear in the same order in the output, but may be arbitrarily mixed with each other; such a mix is called a proper mix. In his attempt to mix things up well, Charlie might have coded the algorithm improperly. Given two streams of m and n digits respectively, and an output of m and n digits, Required:
Determine whether the output is a proper mix of the two input streams or not?

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.
