  The class `bad_typeid` defines the type of objects thrown as exceptions
16
- by the implementation to report a null pointer in a `typeid`
17
- expression ([[expr.typeid]]).

19
- ``` cpp
20
- bad_typeid() noexcept;
21
- ```
22
-
23
- *Effects:* Constructs an object of class `bad_typeid`.
24

25
- ``` cpp
26
- bad_typeid(const bad_typeid&) noexcept;
27
- bad_typeid& operator=(const bad_typeid&) noexcept;

- *Effects:* Copies an object of class `bad_typeid`.

  ``` cpp

  const char* what() const noexcept override;

  ```

36
  *Returns:* An *implementation-defined* NTBS.

38
- *Remarks:* The message may be a null-terminated multibyte
39
- string ([[multibyte.strings]]), suitable for conversion and display as
40
- a `wstring` ([[string.classes]], [[locale.codecvt]])
