Structs as a shorthand for public classes

Structs as a shorthand for public classes

Traditionally, structs serve as data aggregates. However, in C++ a struct can have constructor(s), destructor and member functions just like a class. The only difference between the two is the default access type: a class has by default private access type to its members and derived objects, whereas a struct has by default public access to its members and derived objects. Therefore, structs can be used as a shorthand for classes whose members are all public rather than being confined to the traditional role of ‘plain old data’ containers. A good example for that is the case of abstract classes:

 struct File { //all members are implicitly public	virtual int Read()  = 0; 	File(FILE *);	virtual ~File();};class TextFile: File {//implicit public inheritance; File is a struct	string path; //private member	//...other private members 	public:	int Flush();	int Read();};class UnicodeFile : TextFile { //implicit private inheritance	//...};

What is Metadata?

What is metadata? Well, It’s an odd concept to wrap your head around. Metadata is essentially the secondary layer of data that tracks details about the “regular” data. The regular
