A few random examples typed up during the Final Exam Review
(in the 10 am lab, after the bad projection connector was replaced!)

const int NUM_WIDGETS = 6;
string widget_names[NUM_WIDGETS];

say you have a function handle_strings with the signature:

// signature: handle_strings: string[] int -> bool

I can call handle_strings with argument widget_names
as in the example below:

cout << boolalpha << handle_strings(widget_names, NUM_WIDGETS)
     << endl;

******DYNAMIC ARRAY ALLOCATION EXAMPLE

boa *many_boas;
int num_boas;

cout << "how many boas? " << endl;
cin >> num_boas;

many_boas = new boa[num_boas];

// now, can just use many_boas like a typical array!

for (int i=0; i<num_boas; i++)
{
    cout << many_boas[i].get_color() << endl;
}

delete [ ] many_boas; // use [ ] to free a
                      // dynamically-allocated array's
		      // memory!!!

*************************************
// CONSIDER the following function header:

double oddity(double *p1, 
              double& p2,
              double my_array[],
              int array_size)

// here is the signature for oddity:

// signature: oddity: double* double& double[] int -> double

*************************************
consider the headers:

void do_it(int val1, string name)
int do_that()

If I asked:
Write a C++ statement including a reasonable call to
the function do_it

do_it(13, "Carol");

Write a C++ statement including a reasonable call to
the function do_that

cout << do_that() << endl;
int quant = do_that();
