Built-in (fundamental) C++ data types:

  * integral
    * ''bool'' (''true'', ''false'')
    * ''char'', ''wchar_t''
    * ''int'', ''long'', ''long long''
  * floating point
    * ''float''
    * ''double''
    * ''long double''
  * ''void''

User-defined types:

  * enumerations
  * classes

Also consult:

  * ''<cstdint>''
  * ''<numeric_limits>''
  * ''<cstddef>''

String literals:

  * statically allocated so it's safe to return them from functions

New with C++11:

  * ''alignas''
  * ''alignof''
  * ''std::alignment_of''

Deducing a type:

  * ''auto'' for deducing a type of an object from its initializer; the type can be the type of a variable, a ''const'', or a ''constexpr''.
  * ''decltype(expr)'' for deducing the type of something that is not a simple initializer, such as the return type for a function or the type of a class member.

General stuff:

  * The result of ''sizeof'' is of an unsigned integral type called ''size_t'' defined in ''<cstddef>''. The result of pointer subtraction is of a signed integral type called ''ptrdiff_t'' defined in ''<cstddef>''.
