What is the type of a string literal in C++? [duplicate]

For example, what is the type of the string literal "Hello", const char[6] or const char* ?

The type of the string literal "Hello" is "array of 6 const char".

Ordinary string literals and UTF-8 string literals are also referred to as narrow string literals. A narrow string literal has type “array of n const char”, where n is the size of the string [...]

It can, however, be converted to a const char* by array-to-pointer conversion. Array-to-pointer conversion results in a pointer to the first element of the array.

The Standard defines it as an "array of n const char", so it's const char[n] (n is the size of the string, including the terminating NUL byte).

Section 7, § 2.14.15:

A narrow string literal has type “array of n const char”, where n is the size of the string as defined below, and has static storage duration.
