How can I have two fixed width columns with one flexible column in the center?
...sing width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:
0 = don't grow (shorthand for flex-grow)
0 = don't shrink (shorthand for flex-shrink)
230px = start at 230px (shorthand for flex-basis)
which means: always be 230px.
See fiddle, thanks @TylerH

Is it possible to declare two variables of different types in a for loop?
...tax has been supported in gcc and clang for years (since gcc-7 and clang-4.0) (clang live example). This allows us to unpack a tuple like so:
for (auto [i, f, s] = std::tuple{1, 1.0, std::string{"ab"}}; i < N; ++i, f += 1.5) {
// ...
}
The above will give you:
int i set to 1
double f set...
