问有没有办法在std::remove_if迭代器上使用std::string_view?ENC++中函数指针的用途非常广泛,例如回调函数,接口类的设计等,但函数指针始终不太灵活,它只能指向全局或静态函数,对于类成员函数、lambda表达式或其他可调用对象就无能为力了,因此,C++11推出了std::function与std::bind这两件大杀器。
int foundS1 = name.IndexOf(" "); int foundS2 = name.IndexOf(" ", foundS1 + 1); if (foundS1 != foundS2 && foundS1 >= 0) { name = name.Remove(foundS1 + 1, foundS2 - foundS1); Console.WriteLine("After removing the middle name, we are left with '{0}'", name); } } ...

上文中的”任何改变都会产生新的字符串“,包括字符串的一些操作函数,如str1.ToLower,Trim(),Remove(int startIndex, int count),ToUpper()等,都会产生新的字符串,因此在很多编程实践中,对于字符串忽略大小的比较: if(str1.ToLower()==str2.ToLower())//这种方式会产生新的字符串,不推荐if(string.Compare...
