Chapter 11. PC #6. FileArray Class (page 758) Design a class that has a static method named writeArray. The method should take two arguments: the name of a file and a reference to a double array. The file should be opened as a binary file, the contents of the array should be written to the file, and then the file should be closed. Write a second method in the class named readArray. The method should take one argument: the name of a file. This method should return a reference to a double array. The file should be opened, data should be read from the file and stored in the array, and then the file should be closed. Demonstrate both methods in a program (method main of the same class).
