		Token token;
		analyer=new LexicalAnalyer("test.c","key.txt","limit.txt","operator.txt");
		analyer.Scan("1.txt","2.txt","3.txt");
		System.out.println("词法分析成功,记号表输出到1.txt,符号表输出到2.txt,常数表输出到3.txt");
		System.out.println();
		System.out.println("开始递归下降分析：");
		GrammerAnalyer grammerAnalyer=new GrammerAnalyer("test.c","key.txt","limit.txt","operator.txt", "grammer.txt");
		grammerAnalyer.Analyer();
		System.out.println();
		System.out.println("开始LL(1)分析：");
