The short answer to this question is simple. A method is a function that is associated with a type, that is, a class, a struct, or an enum. This means that every method is a function, but not every function is a method. The long answer is more interestin
When a non-bool x is converted to a bool, non-zero becomes true and zero becomes false, as if you had written x != 0. When bool is converted to non-bool, true becomes 1 and false becomes 0.The type "BOOL" is a Windows type, and it's just a typedef for int. As such, it ...
Any refers to any instance of a class, struct, or enum – literally anything at all. You’ll see this in Swift wherever types are unknown or are mixed in ways that can be meaningfully categorized:let values: [Any] = [1, 2, "Fish"]...

typedef struct { ... } Foo; 声明一个匿名结构并为其创建一个typedef。因此,使用此构造,它在标记名称空间中没有名称,只有 typedef 名称空间中的名称。这意味着它也无法向前宣布。如果要进行前向声明,则必须在标记名称空间中为其指定名称。 在C ++ 中,所有struct/union/enum/class声明都像隐式typedef一样,只要...
