Returns a copy of the underlying view.

1) Copy constructs the result from the underlying view. Equivalent to return base_ ; .
2) Move constructs the result from the underlying view. Equivalent to return std :: move ( base_ ) ; .

Return value

A copy of the underlying view.

Example

A link to test the example online: Compiler Explorer .

Run this code 
#include <print>
#include <ranges>
int main()
{
    static constexpr auto v = {1, 2, 3, 4};
    constexpr auto w{std::ranges::chunk_view(v, 2)};
    std::println("{}", w.base());
}

Output: 

[1, 2, 3, 4]
