test.txt

这个是我在编译原理做的课程设计,一个编译器,包括词法语法分析,结果生成四元式序列,可执行文件也在里面:)

progRAM aaa;{ here is comment line }VAR 
 i,j23,kka: INTEGER;
x4t,asdf: REAL;
BEGIN
   i:=3+5*2.09;
   {comment:******}
   if x4t * asdf <= j23/asdf 
     THEN
     WHILE kka>0 DO
       IF i<0 THEN i:=i+1 ELSE i:=i-1
   ELSE asdf:=.09*2.4
END.
