1 Recursion and activation records

Download, compile and run [ 10fibo.cpp ] and trace the activation records as it executes.

2 Parameter passing

Here are some examples of how a parameter handling works in C++. Download, compile and test [ 10flipper.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, and when the program is changed it still does the same thing.

Note. Call by name is alive and well in C++, if you have time look at [ name.cpp ] for an example of Jensen's device from Algol 60.
