std::reverse_iterator<Iter>::operator=
Min standard notice:
Assigns other.current to current.
# Declarations
template< class U >
reverse_iterator& operator=( const reverse_iterator<U>& other );
(constexpr since C++17)
# Parameters
other: iterator adaptor to assign
# Return value
*this
# Example
#include <iostream>
#include <iterator>
int main()
{
const int a1[]{0, 1, 2};
int a2[]{0, 1, 2, 3};
short a3[]{40, 41, 42};
std::reverse_iterator<const int*> it1{std::crbegin(a1)};
it1 = std::reverse_iterator<int*>{std::rbegin(a2)}; // OK
// it1 = std::reverse_iterator<short*>{std::rbegin(a3)}; // Compilation error:
// incompatible pointer types
std::reverse_iterator<const short*> it2{nullptr};
it2 = std::rbegin(a3); // OK
// it2 = std::begin(a3); // Compilation error: no viable operator= overload
std::cout << *it2 << '\n';
}
