if(tag==1)//tag为1 则读取当前字符

if(tag==2)//tag为2 报错
printf("Wrong!");
}
fclose(f1);
fclose(f2);
return 0;
}

运行出来结果是：
KeyWord if
SingleWord (
Word i
SingleWord >
Digit 1
SingleWord )
Word return
Digit 1
SingleWord ;
Word elsereturn
Digit 0
SingleWord ;

可我想要的结果是：
KeyWord if
SingleWord (
Word i
SingleWord >
Digit 1
SingleWord )
Word return
Digit 1
SingleWord ;
KeyWord else
Word return
Digit 0
SingleWord ;

大家帮忙看看，谢谢啦
