Practice Exercise #1

Part A

Write a C program that tests whether or not the following data types are passed by reference or by value, and prints what it discovers out to the terminal:

int
array of ints

Hypothetically, if your program discovers that an int is passed by value and an array of ints is passed by value, then it should produce output like:

int: pass-by-value
array of ints: pass-by-value

Part B

Write a program that:

defines an array of 10 ints
assigns factorial(x) to array element x, for x in the range 0 through 9, inclusive
copies those array elements into a second array of 10 ints, but in reverse order (i.e., element 0 is factorial(9), element 1 is factorial(8), and so on)
prints out that second array to the terminal
