逐行运行,需要有解释器才能运行(上面的例子,必须在餐馆吃饭),容易找出错误(debug)并调整错误(上面的例子,随时可以调整菜的口味) 编译器:compiler 一次把整个程序都翻译好,然后生成可执行文件(executable file ) 知识点练习: 来自:gfergfer《IGCSE计算机》
字节码解释器是解释执行的,所谓解释执行,就是将Java字节码转成C++代码,再将C++代码编译成本地代码(硬编码),之所以会转成C++代码,是因为HotSpot虚拟机(本文中所说的Java虚拟机都是指HotSpot虚拟机)是C++代码编写的,所以Java字节码指令的底层实现都是由C++代码实现,执行字节码指令其实就是执行对应的C++代码,而执行C++...
It's basically two solutions in one. You can either compile the BASIC programs so that you can run them inside a Java environment/application using the runtime that the project provides. Or you can use the native cross compiler to compile it for the real C64, VIC20 or Commander X16 (no...
In the same way, Zork was compiled to “Z-machine” program files, called ZIP (which was of course used in 1990 by the much more well known PKZIP). To date, the compiler, “Zilch” has not been released, but the language specification and ZIP specifications have, which has led some ...
1) Both compilers and interpreters convert source code (text files) into tokens, both may generate a parse tree, and both may generate immediate instructions. The basic difference is that a compiler system, including a (built in or separate) linker, generates a stand alone machine code program...

(usually very shallow and very wide). It can be a quite inefficient way to represent and work with the data. In my opinion, these are also the conditions under which recursive descent compilers are appropriate, so they can be a good match. But you would not write a Delphi compiler this...
