What''s this? Instruction is a class, so this is a constructor, but what''s with the colon and the "_code(code)"? Never seen that before... Does that call the code''s constructor? If so, why isn''t _opcode() called instead? public: Instruction(opcode code) : _code(code) {}

This construct is called an Intiallizer List. Look it up in your favorite C++ book
