How can I use “sizeof” in a preprocessor macro?
...d.
Preprocessing directives are evaluated before the source is parsed (at least conceptually), so there aren't any types or variables yet to get their size.
However, there are techniques to getting compile-time assertions in C (for example, see this page).

Why is a boolean 1 byte and not 1 bit of size?
...ure can address with its own opcodes. sizeof(bool) must have a value of at least 1, and adjacent bool objects must have their own addresses in C++, so the implementation just has to make them bigger and waste memory. That's why bit fields exist as a special case: the bitfield members of a struct are...
Is there any pythonic way to combine two dicts (adding values for keys that appear in both)?

r[key] += val # You can custom it here

However at least from a C perspective, casting is an appropriate term whether or not you're changing the underlying structure of the data. It simply refers to explicit type conversion. Please explain away my misunderstanding if you can....
