static_cast可以用来进行相关类型之见的转换,比如double 转成 float, float转成 int 以及 有关联的pointer之间,有关联的 class pointer 之间的转换。 ===比如=== float FloatNum = 1.234; int IntNum = static_cast<int>(FloatNum); // IntNum = 1; ===或者=== class BaseClass{ public: BaseClass()...

C 指针的小小实验 更新: 空白指针,也被称为通用指针,是一种特殊类型的指针,可以指向任何数据类型的对象! 空白指针像普通指针一样被声明,使用void关键字作为指针的类型。 The void pointer, also known as the…
ctypes.cast(obj, type)This function is similar to the cast operator in C. It returns a new instance of type which points to the same memory block as obj.type must be a pointer type, and obj must be an object that can be interpreted as a pointer. ...
