The array Template Class (C++11)

The vector class has more capabilities than the built-in array type, but this comes at a cost of slightly less efficiency. If all you need is a fixed-size array, it could be advantageous to use the built-in type. However, that has its own costs of lessened convenience and safety. C++11 responded to this situation by adding the array template class, which is part of the std namespace. Like the built-in type, an array object has a fixed size and uses the stack (or else static memory allocation) instead of the free store, so it shares the efficiency of built-in arrays. To this it adds convenience and additional safety. To create an array object, you need to include the array header file. The syntax is a bit different ...
