Hi there 👋

cpp-intro's Issues

can't call constructor of vector

to reproduct define macro #ISSUE_6

is_category_of() doesn't work on forward_link_list_iterator.

To reproduce compile error.
define ISSUE_2 at main.h.
then, make.
main.cpp:1199:48: error: no type named 'iterator_category' in 'std::iterator_traits<ns::forward_link_list_iterator<ns::forward_link_list<int> > >'

vector<destructor> cannot construct

define macro ISSUE_7 to reproduct problem.

std::advance does not work

define macro ISSUE_3 to reproduce.
error: no type named 'difference_type' in 'std::iterator_traits<ns::forward_link_list_iterator<ns::forward_link_list<int> > >'

invalid operands to binary expression

compile error message(clang++)

error: invalid operands to binary expression ('int' and '__gnu_cxx::__normal_iterator<int *, std::vector<int, std::allocator<int> > >')

target source code

static void test_random_access_iter3() {
  using iterator = std::vector<int>::iterator;
  expect(__LINE__, true,
	 is_category_of< std::random_access_iterator_tag, iterator >());
  
  std::vector<int> v;
  int n = 3;
  
  v.push_back(1);
  v.push_back(2);
  v.push_back(3);
  
  auto iter = std::begin(v);

  n - iter ; // <- The error occurs here
}

std::allocator_traits<Alloc>::construct doesn't work

define ISSUE_4 To reproduce

unexpected destruction.

define macro ISSUE_8 to reproduct

const_reverse_iterator doesn't work

define ISSUE_5
