word_type operator
""_w(const char *w, size_t n)¶ Literal for defining word_type over integers less than 10.
This operator provides a convenient brief means of constructing a word_type from an sequence of literal integer digits or a string. For example,
0123_w
produces the same output asword_type({0, 1, 2, 3})
.There are some gotchas and this operator should be used with some care:
the parameter
w
must only consist of the integers \(\{0, \ldots, 9\}\). For example, there are no guarantees about the value of"abc"_w
.if
w
starts with0
and is follows by a value greater than7
, then it is necessary to enclosew
in quotes. For example,08_w
will not compile because it is interpreted as an invalid octal. However"08"_w
behaves as expected.
Warning
This operator performs no checks on its arguments whatsoever.
- Parameters
w – the letters of the word
n – the length of
w
(defaults to the length ofw
)
- Throws
(None) – This function guarantees not to throw a
LibsemigroupsException
.- Returns
A value of type word_type.
