template< class T = void > struct not_equal_to; (C++14 起) 进行比较的函数对象。除非特化,调用类型 T 上的operator!=。 特化标准库提供 std::not_equal_to 在不指定 T 时的特化,令形参类型和返回类型留待推导。 not_equal_to<void> (C++14) 实现x != y 的函数对象,推导形参类型和返回类型 ...
您使用3个参数调用std::equal,其中https://en.cppreference.com/w/cpp/algorithm/equal表示: 如果范围[first1,last1]等于范围[first2,first2+(last1-first1)),则返回true,否则返回false 在您的案例中,这将导致未定义的行为 将std::equal与4个参数一起使用: std::equal(a.begin(), a.end(), b.begin...
