Yeah, got the numbering wrong as I was experimenting and exploring. The 2nd variant of my code seems to do what it's supposed to do. Or at least mirrors what the original author's example does when I compile it in Visual Studio and run that.
The two I thought were problematic seem to print out the address or value of the pointer, not the output of the two functions, if I'm understanding correctly now. As you say, the functions aren't called.
Hopefully it's useful info for the rather frequent questions here about pointers. I recall one person asking to make an array of function pointers, which this example also happens to illustrate.
It made some concepts clearer for my pointer-phobic brain.
