and trace the activation records as it executes.  This
is not your father's Fibbonaci function!

Hint: you can ask for different sequences of Fibonaci numbers
by changing the arguments when you call the compiled program.
If you output the compiled program into 11fibo for example
you can
.As_is 		11fibo 12 14
for example.
. 2 Parameter passing
Download, compile and test
.See http://www/dick/cs320/lab/11flipper.cpp
which use pass by reference.

Recode it using pass by value of a pointer.
In other words, you may not put `&` in the header of the function.
You must use '*' and '&' as prefix operators in expressions.
When the program is changed it still does the same thing.

Link the fixed and the original code to your web page.

. 4 Call by Name in C++
Note.  Call by name is alive and well in C++, 
if you have time look at
.See http://www.csci.csusb.edu/dick/cs320/c++/name.cpp
for an example of Jensen's device from Algol 60.
