-        math vs cmath, X vs cX
+	c++ is a backwards compatible extension of c, therefore it must provide all the c headers with the exact same semantincs.
 
-        cX puts things in std:: namespace. *always* use it.
-        X.h puts *all* in the global namespace. *never* use it.

+
+        The difference is the following:
+
+        - cX puts things in std:: namespace. *always* use it on new code, since this reduces the probability of a name conflicts, and is the standard c++ way of doing things.
+
+        - X.h puts *all* in the global namespace, it is exactly the same as the c headers. *never* use it in the code.
