Namespaces

• All C++ symbols (variable names, function names, class names) exist within a namespace
• The complete symbol is namespaceName::symbolName
• The only pre-defined namespace is the global namespace
  (its name is the empty string ::varName)
• Standard C++ library: namespace std std::string
