find ( const char_type * ptr, std:: size_t count, const char_type & ch ) ; |
(constexpr since C++17) | |
Searches for character ch within the first count characters of the sequence pointed to by ptr .
See
CharTraits
for the general requirements on character traits for
X::find
.
Parameters
| ptr | - | pointer to a character string to search |
| count | - | the number of characters to analyze |
| ch | - | the character to search for |
Return value
A pointer to the first character in the range specified by
[
ptr
,
ptr
+
count
)
that compares equal to
ch
, or a null pointer if not found.
Complexity
Linear in count .
