This function returns the begin "iterator" of an array. It is useful to

treat an array like an STL container.

For example:
|
|
\code
|
|
int array[10] = { 1, 2, 3, 4, 5 } ;
|
|
std::vector<int> v ;
|
|
std::copy( Begin(array), End(array), std::back_inserter( v ) ;
|
|
\endcode
|
|
|
|
\param array reference to the array
|
|
\return the begin iterator of the array. i.e. \a array itself
|
|
\sa End(), Count()
|
