2 Naming Version/Issue: 1.1/5
link the program because of name clashes. You can avoid that by declaring and defining
names (that would otherwise be global) inside namespaces.
Example:
A namespace is a declarative region in which classes, functions, types and templates can be
defined.
namespace Emc {
}
class Track { ... };
// ...
A name qualified with a namespace name refers to a member of the namespace.
Emc::Track electronTrack;
A using declaration makes it possible to use a name from a namespace without the scope
operator.
using Emc::Track;
Track electronTrack;
// using declaration
It is possible to make all names from a namespace accessible with a using directive.
using namespace Emc;
Track electronTrack;
Array allTracks;
// using directive
// Emc::Track electronTrack;
// Emc::Array allTracks;
The following items could appear rather arbitrary. The importance of these conventions is
simply in fostering a common style and naming across a wide community of programmers.
The benefit is an increase in the readability and maintainability of the produced code,
especially when compared to a situation were each programmer adopts an own naming
convention.

Start class names, typedefs and enum types with an uppercase letter.
Example:
class Track;
typedef vector TrackVector;
enum State { green, yellow, red };
