Kevin Lynch explains the basics of C pointers and memory addresses using visual diagrams.

For more information, see nu32.org. This video is a supplement to the book "Embedded Computing and Mechatronics with the PIC32 Microcontroller," Lynch, Marchuk, and Elwin. It is part of Northwestern University's ME 333 Introduction to Mechatronics. L-comp: Given the code int i, *ip; ip = &i; give one more line of code that sets i equal to 50 without using the variable i.

On “Recommendation for best pointer guide”

I like the explanations where they illustrate the memory like this: link to this video I don't have a favorite but I think about memory like that when I use pointers.

On “I can't understand the last two printf statements”

I wouldn't even know how to do that. I'm just an old man that comes back every couple of years to see if this ever clicks. I'm no programmer. The only thing with pointers I've understood is this: link to this video I can't go from that to get what's happening with argv. Don't worry, I'll go away soon enough. Thanks for your help though.
