2.9 Name Spaces

“Name space” refers to the place the compiler keeps symbols used to refer to various program elements. The place a symbol is kept influences whether two program symbols will conflict. C has two name spaces, but C++ maintains only one name space.

The two C name spaces are:

Variable, function, typedef, and enumerator name space

Structure, enumeration, and union tag name space

In C++, all these names share a single name space.
