Instead of using the syntax ``std::func_name()'', why not declare

using namespace std;

right after your #include and other directives and right before the
spot where you intend to use functions, structs, enums, typedefs, and
classes belonging to the ``std'' namespace. The Gnu C compiler 2.952 and
earlier versions, by default, ignores the ``std'' namespace. In fact,
you can ignore the std namespace altogether when you use gcc or gxx. But
this works only for std namespaces, with other namespaces, you have to
use the ``using'' directive or :: scope resolution operator.

Using ``using namespace std;'' also makes your source cleaner since you
do not have to include the ``std::'' scope resolution everytime you use
something from the std namespace.
