关于c++的指针数组的练习题？

Create a Stats class that represent an array of integers and perform certain
operations on that data

Members are: pointer to an array of integers, size of the array

Methods include (at least, you may add any others you need):

i. a private sort method using insertion sort
ii. a default (no parameter constructor)

iii. a destructor
iv. a method that takes and array of integers and its size and

copies it to the internal array
v. methods to find the mean, mode and median of the data in the

internal array
vi. a printData method to print out the array

vii. a printStats method to print out the stats

Answer 1

个人觉得也有点小麻烦哦.... 这么麻烦, 都懒得给你伪代码了...
你按照它要求一个个做就是啊...
要求那么清晰, 你唯一任务就是实现它.
比如1, 实现一个sort 的私有函数, 用插入排序实现sort...

奇怪的是, stats 是啥玩意? =,=! 统计?状态?? 统计虾米?

是蛮简单，写完了谢谢

恩，国外上学？汗
最近看到好几个全英文的编程题，奇怪。。。

问主，觉得满意请采纳哟！(╯3╰)如果还有什么问题，也可以继续问我！

Answer 2

r u sure u gotta everything covered? :-) just kidding, dude.
Were you allowed to use those fancy STL containers & algorithms？ if yes, life's much easier.

The tricky part is not how to construct a trivial states class, it is how to get mode. The mode is not necessary to be unique, it could be none, or multiple values. The data series like this one below:
1 2 3 5 6 7
has no mode at all.
But:
1 1 1 2 2 3 4 4 5 5 5
have two modes, 1, 5, with a frequency of 3, respectively.

Answer 3

比较麻烦的一个类，要有构造函数、析构函数，运算符重载

还好，我之前有些不太懂，不过已经完成谢谢
