2)等价于find(basic_string_view(std::addressof(ch),1), pos)。 3)等价于find(basic_string_view(s, count), pos)。 4)等价于find(basic_string_view(s), pos)。 参数 v-要搜索的子串 pos-要开始搜索的位置 count-要搜索的子串长度 s-指向要搜索的字符串的指针 ...
basic_string的元素是连续存储的,即对于basic_strings,对[0,s.size())中的任意n有&*(s.begin()+n)==&*s.begin()+n,或等价地,指向s[0]的指针能传递给期待指向CharT的空终止(C++11 起)数组首元素指针的函数。 std::basic_string满足知分配器容器(AllocatorAwareContainer)(但不使用定制的construct...
The elements of abasic_stringare stored contiguously, that is, for a basic_strings,&*(s.begin()+n)==&*s.begin()+nfor any n in[0, s.size()), or, equivalently, a pointer tos[0]can be passed to functions that expect a pointer to the first element of acharT[]array.(seit C++...

For instance, if the user inputs cppstring, the code tries to find cpp/string. Partial Path Match: If the previous two matches fail, the code attempts a partial path match. This is the most complex part, allowing users to input a combination of partial paths, such as matching functional...
