Most types do not have a literal. Classes do not have one. Pointers, references, r-value references have none, as well. <code>void</code> does not have a literal. 

You mentioned <code>string</code> which also does not have a literal, it only has a constructor that takes a <code>const char*</code> literal! C++ calls this constructor implicitly, when assigning a <code>const char*</code> literal to a string.

Adding to the list, there's no literals for <code>signed char</code>, <code>unsigned char</code>, <code>short</code>, <code>unsigned short</code>.

You should probably think in terms of the limited list of types for which there are literals, rather than the types for which there are not. Literals are for:

<ul>
<li>bool</li>
<li>char, wchar_t, char16_t, char32_t</li>
<li>"array of const" char, wchar_t, char16_t, char32_t (that is, string literals)</li>

<li>long, unsigned long</li>

Only arithmetic types have their own literals. The exception is string literals that has type of <code>const char arrays</code> and not so fer introduced in the C++ 11 <code>nullptr</code> of type <code>std::nullptr_t</code>

<h2>Literals explained:</h2>

integer-literal

An integer literal is a sequence of digits that has no period or exponent part. 

example: <code>1</code>

character-literal

A character literal is one or more characters enclosed in single quotes, as in ’x’, optionally preceded by
one of the letters u, U, or L, as in u’y’, U’z’, or L’x’, respectively.

’ c-char-sequence ’

u’ c-char-sequence ’

U’ c-char-sequence ’

L’ c-char-sequence ’

example: <code>'a'</code>, <code>'ab'</code>, <code>'\''</code>, <code>L'0'</code>, <code>'('</code>

floating-literal

A floating literal consists of an integer part, a decimal point, a fraction part, an e or E, an optionally signed
integer exponent, and an optional type suffix. The integer and fraction parts both consist of a sequence of
decimal (base ten) digits. Either the integer part or the fraction part (not both) can be omitted; either the
decimal point or the letter e (or E ) and the exponent (not both) can be omitted. The integer part, the
optional decimal point and the optional fraction part form the significant part of the floating literal. The
exponent, if present, indicates the power of 10 by which the significant part is to be scaled.

example: <code>123.456e-67</code>, <code>.1E1f</code>, <code>42.</code>, 1<code>3e3</code>

string-literal

A string literal is a sequence of characters (as defined in 2.14.3) surrounded by double quotes, optionally
prefixed by R, u8, u8R, u, uR, U, UR, L, or LR, as in "...", R"(...)", u8"...", u8R"(...)", u"...",
uR"* ̃(...)* ̃", U"...", UR"zzz(...)zzz", L"...", or LR"(...)", respectively.

encoding-prefixopt " s-char-sequenceopt "

encoding-prefixopt R raw-string

example: <code>"me"</code>, <code>L"you"</code>

boolean-literal

The Boolean literals are the keywords <code>false</code> and <code>true</code>. Such literals are <code>prvalues</code> and have type <code>bool</code>.

<pre><code>false
true
</code></pre>

pointer-literal

The pointer literal is the keyword <code>nullptr</code>. It is a prvalue of type <code>std::nullptr_t</code>.

<pre><code>nullptr
</code></pre>

user-defined-literal

Overload of <code>operator""</code> that allows to interpret literal using user-defined logic.

example:

<pre><code>typedef double signalf;
constexpr signalf operator"" _percent( long double val) { return val / 100 ; }

std::cout &lt;&lt; 12.34_percent; // prints 0.1234
</code></pre>

Bjarne Stroustrup's Programming Principles and Practice Using C++ (Sixth Printing, November 2012) refers to <a href="http://cs.nyu.edu/courses/fall11/CSCI-GA.2110-003/documents/c++2003std.pdf" rel="nofollow noreferrer">ISO/IEC 14882:2003</a> as the relevant C++ standard.

There are several kinds of literals.

literal:
 integer-literal
 character-literal
 floating-literal
 string-literal

</code></pre>

Apparently, this is an exhaustive list; and because there can be many more types than there are kinds of literal in that list, the answer is: no, not every type has a corresponding literal.

N.B. for the C++11 case, please see <a href="https://stackoverflow.com/a/22199042/82216">Lizusek's answer</a>.

According to Bjarne Stroustrup's Programming Principles and Practice Using C++ (Sixth Printing, November 2012), "each of [the] types [<code>int</code>, <code>double</code>, <code>char</code>, <code>string</code>, and <code>bool</code>] has its own characteristic style of literals" (p.63).

In §A.2 of the same book, additional varieties of <code>int</code> (unsigned; long) and floating-point-literals are mentioned, as well as the (null) pointer literal.

Does every type have a corresponding literal?
