This is not a Windows question. It is a language question.
C
C is weird. Some identifiers can be declared multiply
as forward. You can have the same name sometimes for
things that are of different type. Not to speak of macro's

Look into C/C++ Namespaces.  That explains things reasonably well.

Pascal
If you declare multiple identifiers in the same namespace
you are hit on the head. You can have nested namespaces
and there is no conflict, the inner namespace counts.

Pascal is compiled in a single pass through the source code, so
everything must be defied before it is first used.  Unlike C/C++,
which has a multipass compiler and linker.  This was done because
Pascal was intended for teaching programming, and the load in the
university's computers was from compiling buggy student homework code
time and time again, while C was intended to replace assembly in the
Unix operating system.

Forth
You can use the same name for multiple objects.
The name last defined counts. You get at most a warning.

Forth is interpreted, and is a pure pushdown language, like a HP
calculator using RPN.
