3. No non-const ref parameters to functions, use pointers.
They want a visible "&" at call site for output parameters.
e.g. "read(&var)" so that you don't have to look the function
up in the docs.
Coming from a Quick/Turbo Basic/Turbo Pascal background, I
never understood the C culture about function parameters.
Just another example of C being unsafe.
C is unsafe, but it is desirable to make it visible at the call
site that you are returning a value through a parameter.

Interviewer: Just a minute. What about references? You must
admit, you improved on 'C' pointers.
Stroustrup: Hmm. I've always wondered about that. Originally, I
thought I had. Then, one day I was discussing this with a guy
who'd written C++ from the beginning. He said he could never
remember whether his variables were referenced or dereferenced,
so he always used pointers. He said the little asterisk always
reminded him..
