operator<,<=,>,>=(std::basic_const_iterator<Iter>)

Since C++23

Compare a basic_const_iterator with another value. These function templates are used when the left operand is not a basic_const_iterator.

# Declarations

template< /*not-a-const-iterator*/ I >
friend constexpr bool operator<( const I& x, const basic_const_iterator& y )
requires std::random_access_iterator<Iter> && std::totally_ordered_with<Iter, I>;

(since C++23)

friend constexpr bool operator>( const I& x, const basic_const_iterator& y )
requires std::random_access_iterator<Iter> && std::totally_ordered_with<Iter, I>;

# Parameters

# Notes

If the left operand is a basic_const_iterator, the member comparison functions are used.

# Example

#include <iterator>
 
int main()
{
    static int arr[1];
    static constexpr std::basic_const_iterator<int*> it = std::end(arr);
    static_assert(arr < it);
}
