C++：Array

Array是固定大小的容器，定义时要显式的指定大小。

可以修改array中元素的值，但不能向array中插入和删除元素.

array在栈上为元素分配内存。

array<TYPE, SIZE>

swap(arr1,arr2);　　//具有线性时间复杂度

arr1.swap(arr2);

.fill(VALUE)　　//填充值

.size()

Iterators

begin

Return iterator to beginning  (public member function )

end

Return iterator to end  (public member function )

rbegin

Return reverse iterator to reverse beginning  (public member function )

rend

Return reverse iterator to reverse end  (public member function )

cbegin

Return const_iterator to beginning  (public member function )

cend

Return const_iterator to end  (public member function )

crbegin

Return const_reverse_iterator to reverse beginning  (public member function )

crend

Return const_reverse_iterator to reverse end  (public member function )

 

 for ( auto rit=myarray.crbegin() ; rit < myarray.crend(); ++rit )
