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

I satisfies the exposition-only concept /*not-a-const-iterator*/ if and only if it's not a specialization of basic_const_iterator .

These functions are not visible to ordinary unqualified or qualified lookup , and can only be found by argument-dependent lookup when basic_const_iterator < Iter > is an associated class of the arguments.

Parameters

x, y - iterators to compare

Return value

1) x < y. base ( )
2) x > y. base ( )
3) x <= y. base ( )
4) x >= y. base ( )

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);
}
