find( const char_type* ptr, std::size_t count, const char_type& ch );
(constexpr since C++17)
find( const char_type* ptr, std::size_t count, const char_type& ch );
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.
[edit] Parameters
ptr
-
pointer to a character string to search
count
-
the number of characters to analyze
ch
-
the character to search for
[edit] 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.
[edit] Complexity
Linear in count.
