static const char_type*
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.
