For two arrays A and B that are already in ascending order, write a program to mingle them into a new array ordered C evenly, the size of C is varied, depending on the values of A and B: the even-indexed (the index starts from 0) elements come from A while odd-indexed elements are from B. For instance, if A is (1,4, 10,12): B is 12.3,10, 11) then the new array C is (1, 2,4,10,12). If a black-box test approach will be used, how many test cases should you design?

The file sales data.xlsx contains monthly sales amounts for 40 sales regions. write a sub that uses a for loop to color the interior of every other row (rows 3, 5, etc.) gray. color only the data area, columns a to m. (check the file colors in excel.xlsm to find a nice color of gray.)

Which tab should you open to find the option for adding a header?

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.
