Namespaces
Namespaces
Namespaces provide a method for preventing name conflicts in large projects.
Symbols declared inside a namespace block are placed in a named scope that prevents them from being mistaken for identically-named symbols in other scopes.
Multiple namespace blocks with the same name are allowed. All declarations within those blocks are declared in the named scope.
Syntax
namespace ns_name { declarations } | (1) | |
inline namespace ns_name { declarations } | (2) | (since C++11) |
namespace {
 |
