std::basic_...emove_prefix(3) C++ Standard Libarystd::basic_...emove_prefix(3) NAME std::basic_string_view::remove_prefix - std::basic_string_view::re- move_prefix Synopsis constexpr void remove_prefix( size_type n ); (since C++17) Moves the start of the view forward by n characters. The behavior is undefined if n > size(). Parameters n - number of characters to remove from the start of the view Return value (none) Complexity Constant. Example // Run this code #include <iostream> #include <algorithm> #include <string_view> int main() { std::string str = " trim me"; std::string_view v = str; v.remove_prefix(std::min(v.find_first_not_of(" "), v.size())); std::cout << "String: '" << str << "'\n" << "View : '" << v << "'\n"; } Output: String: ' trim me' View : 'trim me' See also remove_suffix shrinks the view by moving its end backward (C++17) (public member function) http://cppreference.com 2022.07.31 std::basic_...emove_prefix(3)
