说明：  C语言的扩充PL0文法编译器，支持函数，数组类型，及记录类型，支持输入输出，最后生成虚拟机代码并解释执行。这是我编译原理的课程设计，大家看一看。
(C language compiler grammar PL0 expanded to support the function, the array type, and record type, to support the input and output, the last generation of virtual machine code and interpreted. This is my compiler course design principles, we take a look at.)
