A namespace is a group of related identifiers.
namespace ns {
int i;
double d;
}
Inside namespace ns, i and d can be used normally. Outside namespace ns, i is called ns::i and d is called ns::d. To import i into the current scope, say "using ns::i;". To import all identifiers in ns into the current scope, say "using namespace ns;". Namespaces can be nested:
namespace ns1 {
namespace ns2 {
int i;
}
int i;
}
The i in namespace ns1 is fully qualified as ns1::i. The i in namespace ns2 is fully qualified as ns1::ns2::i. The two variables are distinct. Inside ns2, i refers to ns1::ns2::i; inside ns1, i refers to ns1::i.

I assume you mean using lower case letters. By convention, C and C++ standard libraries use lower-case naming conventions. This makes it easy to identify functions and types that belong to the standard library. When defining your own types, a leading capital is preferred. All capitals typically denotes a macro definition.
