一个面试时的机试题
有一段数据，共15行6列，内容如下：
7272, "车江 ", "转扣预存 ",200704, "衡南县 ",+0000000022675.73
7273, "车江 ", "转扣预存 ",200704, "衡南县 ",+0000000011322.80
7273, "车江 ", "转扣预存 ",200704, "衡南县 ",7322.80
7283, "向阳桥 ", "转扣预存 ",200704, "衡南县 ",-0000033289.55
7283, "向阳桥 ", "转扣预存 ",200704, "衡南县 ",289.55

12052, "江口 ", "转扣预存 ",200704, "衡南县 ",02e574.79


将该数据存储在文本文件A中
要求读入该文件，然后把第6列是正确数值的行取出，按第2列升序排列，再写入到文件B中；把第6列不是正确数值的行写入到文件C中

没测试过，只是编译过去了，你调试一下！
