reference       at( size_type pos );		(since C++11)
constexpr const_reference at( size_type pos ) const;		(since C++11)

Returns a reference to the element at specified location pos, with bounds checking.

If pos not within the range of the container, an exception of type std::out_of_range is thrown.

Parameters

pos

-

position of the element to return

Return value

reference to the requested element

Exceptions

std::out_of_range if !(pos < size()).

Complexity

Constant

Notes

Const version is marked as constexpr since c++14
