The code has generic implementation of queue class (Queue) with simple operations such aspush()andpop(). Thefoo()doesintspecialization, andbar()doesstring. The declaration and definition are all in one header file,template.h. Each of thefoo.cppandbar.cppincludes the sametemplate.hso that the...

The _name, _result_type, etc. are all static arrays defined in the Bytecodes class. The subscript is the Opcode value, and the stored values are name, result_type, etc. The definitions of these variables are as follows: const char* Bytecodes::_name [Bytecodes::number_of_codes]; ...
