What happens to global and static variables in a shared library when it is dynamically linked?
...tions) are never visible from outside a module (dll/so or executable). The C++ standard requires that these have internal linkage, meaning that they are not visible outside the translation unit (which becomes an object file) in which they are defined. So, that settles that issue.

What is the difference between public, protected, package-private and private in Java?
...I control. (While not Java syntax, it is important for this discussion).
C++ defines an additional level called "friend" and the less you know about that the better.

A note on fixed point
Binary fixed point numbers can also work well as a substitute for floating point, as is evident from the four basic arithmetic operations:

When to use std::begin and std::end instead of container specific versions [duplicate]
...ld probably use c.begin() due to inertia. I would expect new text books on C++ to recommend the free function version (as it is never worse and sometimes better), but that has to catch up with common usage.

Why is f(i = -1, i = -1) undefined behavior?
...ans a type like a int, float, or a pointer (see What is a scalar Object in C++?).
Second, it may seem more obvious that
f(++i, ++i);
would have undefined behavior. But
f(i = -1, i = -1);
is less obvious.
A slightly different example:
int i;
f(i = 1, i = -1);
std::cout << i <<...
What is the strict aliasing rule?
...ably has instructions to load buff's contents. Then again, maybe you're in C++ and this is some templated header only implementation that the compiler thinks it can inline. Or maybe it's just something you wrote in your .c file for your own convenience. Anyway undefined behavior might still ensue. E...
