struct vs class

Applies to: cpp

In C++, struct and class are nearly identical; the only language difference is default access (struct members are public, class members private). By convention, struct is used for plain data bundles and class for types with hidden state and a method interface (encapsulation).

struct Point { double x, y; };          // plain data, public
class Robot { public: void drive(); private: double x_; };  // encapsulated
