[c/en] mostly word clarification and extra descriptions (#4222)

* Adds extra clarity to enum value assignment.

The previous statement shows only 1 way to declare enums, and it happens
that they specify a starting value. I clarify that a starting value is
not necessary and that all enum value could contain user specified
values.

* Added clarity to `includes` section.

specified that angle brackets are for system libraries and not just
standard libs. I also added an example of relative paths in the local
include statements.

* Added more clarity for function prototyping and main return vals.

I cleaned up some formatting; then added some clarity to how function
prototyping works, as well as recommend techniques.

* Fixed the mention of character sizes. they are not always 1 byte

* Added clarity about floating point arithmetic.

The previous comments on floating points made it feel like there was
something broken with doing comparison and arithmetics with floating
point types. I added clarity about how floats are stored in memory and
why they seem to behave strangly when used in arithmetic expressions.

* reworded boolean stuff for better clarity on _Bool type in C99

* Adds not about binary assignment

* Added clarity for value roll over

* Added section on multiple return values.

C doesnt allow returning of multiple values, so i added a section on
returning multiple values through pointers.

* added section break for printing special characters

* fix typo
