额，民那，由于代码比较长，以免你们的滚动条缩小了，所以设置了回复隐藏~请不要介意。
这个代码弄了我很久了。问题就是在于原本如果我不用remove()这个函数直接在NewMenu类里new一个游戏面板的时候方块是可以上下左右移动的【请不要吐槽俄罗斯方块不能向上！】
后来由于要有界面友好性所以才搞了个开始面板，然后通过按钮触发事件，跳转到游戏面板。问题是！明明我已经对方块注册了一个键盘监视器，但是就是木有反应，谁能告诉我为神马！？求解决！@125#
【代码神马的略略有点不整齐，希望不要介意~~~】
ps:话说我能不能设置回帖奖励~~？

问题是这样子的...在WIN-TC下可以运行：77：...但是在平均分和最大值最小值那里有问题：82：..说什么不可移动的指针(地址常数)赋值在 *** 函数中..我们不学指针变量..怎么才能改过来呢?求高手帮忙啊：84：...我把所有源代码都贴上来..

ninja 发表于 2012-5-27 16:49那就10個吧，那你報錯信息拿出來看看啊
大概是这样..在输入完学生成绩后(比如10次成绩是1到10)..然后查看全部学生成绩..查看的成绩不是1到10..而是一些其他的数..而且都是三到四位数...而且最大值最小值也不对..平均值也不对..总之就是关于分数的显示的都有问题..

额。我在百度文库看到一个LZSS压缩算法的实现……我反正已经晕了#16！
PLUS：我下载下来，用notepad++把Tab全部换成4个空格后，编译了一下，过了。然后试着用了一下，也OK，所以就发上来了……
