Working with arrays and functions

- It's really nothing to pass an array to a function.…Doing so doesn't require any magic or secret incantations.…It does, however, require acceptance of the fact…that arrays and pointers behave similarly.…Don't let that freak you out.…When you pass an array to a function…you're passing the base address of the array in memory,…that's a pointer.…Open exercise 04-04_arrayfunc1.…This code is a modification from an earlier exercise file,…the one that sorts an array of random values.…

In this modification I've moved…the major operations out of the main function…and put each into its own function.…All the functions are prototypes starting at line seven.…Each function has the same argument, an integer array.…At line seven I've used array notation, that's fine,…and in lines eight and nine, I've used pointer notation.…They're all the same.…In fact, I'll edit line seven to use pointer notation.…Each of the functions is called…by specifying the array name only.…

You see this in the main function…at lines 16, 20, 23 and 27.…
