9.2.9.3 Simple type specifiers [dcl.type.simple]

The simple type specifiers are

The component name of a type-name is the first name in it.

A deducible template is either a class template or is an alias template whose defining-type-id is of the form

[Note 1:

An injected-class-name is never interpreted as a template-name in contexts where class template argument deduction would be performed ([temp.local]).

— end note]

The other simple-type-specifiers specify either a previously-declared type, a type determined from an expression, or one of the fundamental types ([basic.fundamental]).

Table 17 summarizes the valid combinations of simple-type-specifiers and the types they specify.

When multiple simple-type-specifiers are allowed, they can be freely intermixed with other decl-specifiers in any order.

[Note 2:

It is implementation-defined whether objects of char type are represented as signed or unsigned quantities.

The signed specifier forces char objects to be signed; it is redundant in other contexts.
