程序没有写输出部分，所以没有输出C代码，结果只有：



firstcheck.txt：　　输出每个left的first，可以检查first有无错



table.txt:　　用串来表示table中的值，可以检查table是否正确，但只有在表格小的时候才能看出来



forusetable.txt:　　输出的是table中真实的值，-1表示erro，其他值要参照程序里producer的数量，和状态总数来表示其意义，也就是说要用我上学期写的程序来检验表格，还需要根据这次yacc程序来修改读表是动作的确定，但只需要改动几行就行了，总之我没能完成输出麻烦却是很多-Program did not write the output section, there is no output C code, the result only: firstcheck.txt: the output of each left the first, you can check whether the fault first table.txt: use strings to represent the table of values, you can check the table is correct , but only when the table can be seen in small forusetable.txt: the output is real value in the table,-1, said erro, other values should follow the Procedures li producer' s number, and state the total number to express the meaning, that is want to spend my last semester to write a program to test form, also need to read the yacc program to modify the action table is set but only change a few lines on the line, a word I did not complete the output is a lot of trouble
