"Not yet". And no need for an official education.

It's a good thing you work mostly at night, because I think your friend is about to become your day job.

Well, he has a day job too, but he does some programming so I'm not starting from scratch.

Said well.
Here is a C sample using pointers.
Using my rule of keeping pointers from being too saltly, I keep them at a somewhat controlled level
(this is mostly pseudo code so don't cry foul if you see syntax boo-boos
and/or use it and it crashes).
The point is pointers can be very powerful, but must be used with care and with restraint.
/* entry points for routines that do something */
extern int sub1();
extern int xyz();
extern int abc();
extern int subx();
/* put their addresses into a table */
...
struct { int (*action)() } cmd[] = {
sub1,
xyz,
abc,
subx
};
...
int execute_command( char *arguments )
{
int (*go)();
int err;
/* determine index i into the address table using whatever parsing is need to
identify the command intended by the user or the system
*/
go = (int (*)()cmd[i];
/* execute the routine selected by index i */
err = (*go)( arguments );
/* returns error code */
return( err );
}

I'm probably not going to get into jump tables in my article, but you'll be able to create them by building on the techniques I present.

I am not C++ expert, but as I understand it, C is a subset of C++, ergo, anything you can do in C, one can do in C++. This might not be 100% true, but pointers for sure.

I'm as much export as you.
How is it relevant that you are an export?
Assuming you know perpendicular lines, explain .NET without the term "reference".

In 1980, I was introduced to pointers (by way of Pascal). They made perfect sense to me then as they do now.

I was introduced to pointers using PL/I in grad school. Very cool language. Not quite as down and dirty as C, but the compiler general kept it clean. Amazing optimizing compiler and a great language syntax. Too bad it was IBM OS system language so proprietary at the time. C slowly became the go to language at the time for me. Pascal was very nice. Clean and clear. But I went the C route.

I remember PL/1. My graduate CS program decided to instead use Pascal, and then switched to C. We're probably of the same vintage. I completed my MS (CS) degree in 1984.

I completed my MS in 1978. (MSMCD) MS in Mathematics-Computer_Science-System_Design one of the first to offer a sort of triple major. The grad school was pretty young and small so they spread us around various faculty specialties to keep everyone busy. Loved it. It even included some courses in digital electronics. Did you do an wire-wrapping of circuits?

Yes, because I transferred from an MS (Physics) program, I was required to take a few undergrad courses in digital circuit design. We were given a "breadboard in a suitcase" that included a PSU, clock, input switches and output LEDs, and our assignments were implemented as wire wrapped circuits on the suitcase. I have very fond memories of those days! Some of my most fun courses were Assembly Language and Compiler Construction I and II, and my Master's theses. (I got permission to do two because I was working under two professors.)

Yup, we had similar experiences. We used a similar breadboard in a suit case product with similar I/O stuff. Compiler design was a favorite. Still use some the techniques in code, especially parsing user inputs. Did not do much actually assembly coding, but as part of the compiler design courses, we had to create our own assembly language and a simulator written in Fortran, running on a Data General Eclipse mini-computer (not so mini by today's std) about 1 computer rack in size, to execute it. Did many an all-nighter. Went from punch cards to dumb terminals to micro-computers. I worked in the same lab after graduating so my experiences there spanned into the early 80's. Good times indeed.

Thanks, I try. It's going to take me longer than usual it seems. It's a pretty involved topic, and I have to take breaks. It's not so much that it's long, but there are a lot of angles to cover and if I don't clear my head periodically I forget to include some.

If you article includes C++ smart pointers you should include guidelines such as Herb Sutter's guidelines...
