well, both are used to make use of a library, even if what they do and 
how they work is considerably different.

both also have a word starting with the same letter and appear near the 
top of a source file, and are vaguely similar looking, also sort of 
making them "similar".


I also did once see a person try to do something like (in C++):
#include <javax.swing>

and then respond in their defense that "C++ and Java were basically the 
same thing"... (nevermind if they are not...).

well, there is an important difference here:
you can't use 'using' to see a namespace which hasn't already been 
included, and also 'using' is typically used differently as well.

so, it is more like comparing C / C++ #include and C# using.
