综合练习：编程实现小学生算术练习系统，要求主菜单包括５项（加法，减法，乘法，除法，退出），而前４项中每一项又包括子菜单（子菜单包括４项：一级练习，二级练习，三级练习，返回），其中一级实现１０以内的整数运算，二级实现５０以内的整数运算，三级实现１００以内的整数运算．进入某一级后，反复练习（由机器产生两个随机数，用户输入运算结果，输出正确＂ＲＩＧＨＴ＂或者错误＂ＷＲＯＮＧ＂），等用户选择＂返回＂后，给出本级题目中计算正确的百分比．

这道题小Ｄ不思其解！请来帮帮！

无奈本人新学C++,偶也不懂!!

顶顶!!!

晕啊!
有没有人会啊!
急救中啊!

我用VC还不会做，不过用VB做起来还是很简单的呦！哈哈，说了一句废话！不好意思！

用ＴＣ做可以做出来吗？

有那位高手可以来帮帮忙啊!
谢谢啦~!

vc 很简单啊

我是菜鸟,前几天写个学生管理的,我想来试试,请楼主把"１０以内的整数运算"解释清楚下,不知道是两个操作数是10以内,还是结果是10以内,谢谢~
还有除法是不是只要整除的~

都写出来了
我今天才看见楼主发的的
