std::basic_...last_not_of(3) C++ Standard Libary std::basic_...last_not_of(3) NAME std::basic_string_view::find_last_not_of - std::ba- sic_string_view::find_last_not_of Synopsis constexpr size_type find_last_not_of( basic_string_view v, size_type pos = npos ) (1) (since C++17) const noexcept; constexpr size_type (2) (since C++17) find_last_not_of( CharT c, size_type pos = npos ) const noexcept; constexpr size_type find_last_not_of( const CharT* s, size_type pos, size_type count ) (3) (since C++17) const; constexpr size_type (4) (since C++17) find_last_not_of( const CharT* s, size_type pos = npos ) const; Finds the last character not equal to any of the characters in the given character sequence. 1) Finds the last character not equal to any of the characters of v in this view, starting at position pos. 2) Equivalent to find_last_not_of(basic_string_view(std::addres- sof(c), 1), pos). 3) Equivalent to find_last_not_of(basic_string_view(s, count), pos). 4) Equivalent to find_last_not_of(basic_string_view(s), pos). Parameters v - view to search for pos - position at which to start the search count - length of the string of characters to compare s - pointer to a string of characters to compare ch - character to compare Return value Position of the last character not equal to any of the characters in the given string, or npos if no such character is found. Complexity O(size() * v.size()) at worst. Example // Run this code #include <string_view> using std::operator""sv; int main() { static_assert(1 == "BCDEF"sv.find_last_not_of("DEF")); // ^ static_assert(2 == "BCDEFG"sv.find_last_not_of("EFG", 3)); // ^ static_assert(2 == "ABBA"sv.find_last_not_of('A')); // ^ static_assert(1 == "ABBA"sv.find_last_not_of('A', 1)); // ^ } See also find find characters in the view (C++17) (public member function) rfind find the last occurrence of a substring (C++17) (public member function) find_first_of find first occurrence of characters (C++17) (public member function) find_last_of find last occurrence of characters (C++17) (public member function) find_first_not_of find first absence of characters (C++17) (public member function) find last absence of characters find_last_not_of (public member function of std::basic_string<CharT,Traits,Allocator>) http://cppreference.com 2022.07.31 std::basic_...last_not_of(3)
