< cpp‎ | string‎ | char traits
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.

[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 [ptrptr + count) that compares equal to ch, or a null pointer if not found.

[edit] Complexity

Linear in count.
