A. write a function that takes an array of ints, and the size of the array – another int. it also returns a double. call this one ‘average.’ return a double that is the average of the values in the array. demonstrate that it works by finding the average of an array with these values {78, 90, 56, 99, 88, 68, 92}.

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.

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.
