I need to find the size of a class or struct in bytes, I did know how to do
it but I forgot and I can't find anything that tells me (I had a book with
it in but I lost it). You would think this kind of thing would be pretty
easy to find information on.

The sizeof operator:
sizeof yourclassorstructhere
It gives the size of your class or struct in units of the size of char.
(Which is usually a byte.)

Which is /by definition/ a byte. Always.

The sizeof operator:
sizeof yourclassorstructhere
sizeof(some_type)
or
sizeof an_instance_of_some_type
[Using parenthesis in this second case wouldn't be incorrect, but would
obfuscate its purpose.]

Just to add up clarity, the bitwise size of this c++ byte may be more
than 8 bits. This is different than more widely perceived term "byte"
in context of marketing materials for specific platforms, where it is
understood to be 8 bit in size. In c++, byte is defined as unit of
addressability.
