A namespace allows the application to be partitioned in multiple sections. Namespaces create local scopes and therefore can provide multiple definitions of the same name. The general form of a namespace is:

namespace namespace_name {

}

For example:

namespace List {

int Count;

}

There are two ways to access variables declared in a namespace. You can provide the namespace followed by the :: operator and then the variable name:

List::Count = 10;

Or by adding the entire namespace to the current scope with the using keyword:

using namespace List;

Count = 10;
