binary_function is deprecatedinC++11and removedinC++17. binary_function is deprecated in C++11 and removed in C++17.(c++17已经移除了binary_function); 解决办法:将vs c++17设置为 默认(ISO C++14 标准)即可; 二.猜你喜欢
(C++17 中移除) binary_function 是用于创建拥有二个参数的函数对象的基类。 binary_function 不定义 operator() ;它期待导出类将定义此运算符。 binary_function 只提供三个类型—— first_argument_type、 second_argument_type 和result_type——为模板形参所定义。 一些标准库函数适配器,如 std::not2 ...
std::function 是一个可调用对象包装器,是一个类模板,可以容纳除了类成员函数指针之外的所有可调用对象,它可以用统一的方式处理函数、函数对象、函数指针,并允许保存和延迟它们的执行。 定义格式:std::function<函数类型>。 std::function可以取代函数指针的作用,因为它可以延迟函数的执行,特别适合作为回调函数使用。它...
