WebType classification The C++ type system consists of the following types: fundamental types (see also std::is_fundamental ): the type void (see also std::is_void ); the type std::nullptr_t (see also std::is_null_pointer ); (since C++11) arithmetic types (see also std::is_arithmetic ): The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type:
