NAME¶
std::ranges::stride_view::iterator::operator[] - std::ranges::stride_view::iterator::operator[]
Synopsis¶
constexpr decltype(auto) operator[]( difference_type n ) const
(since C++23)
requires ranges::random_access_range<Base>
Returns an element at specified relative location.
Equivalent to: return *(*this + n);.
Parameters¶
n - position relative to current location
Return value¶
The element at displacement n relative to the current location.
Example¶
// Run this code
#include <ranges>
int main()
{
constexpr static auto v = {'a', 'b', 'c', 'd', 'e'};
constexpr auto view{v | std::views::stride(2)};
constexpr auto iter{view.begin() + 1};
static_assert(*iter == 'c');
static_assert(iter[0] == 'c');
static_assert(iter[1] == 'e');
}
