新手不知道对不对
class CArray{
  public:
    CArray(const std::string& str){a[]=str;};
    CArray(const CArray& var){a[]=var.a;};
    ~CArray(){};
    void getstr()const{cout<<a;};
    int getvalue()const{return sizeof a/sizeof a[0];};
    const char getnumber(const int m)const{return a[m];};
  private:
    char a[];
}

写代码的时候总不是很自信
代码肯定有不足之处
不知道写的对不对

CArray Class Members
Construction

CArray Constructs an empty array.

Attributes

GetSize Gets the number of elements in this array.
GetUpperBound Returns the largest valid index.
SetSize Sets the number of elements to be contained in this array.

Operations

FreeExtra Frees all unused memory above the current upper bound.
RemoveAll Removes all the elements from this array.

Element Access

GetAt Returns the value at a given index.
SetAt Sets the value for a given index; array not allowed to grow.
ElementAt Returns a temporary reference to the element pointer within the array.
GetData Allows access to elements in the array. Can be NULL.

Growing the Array

SetAtGrow Sets the value for a given index; grows the array if necessary.
Add Adds an element to the end of the array; grows the array if necessary.
Append Appends another array to the array; grows the array if necessary
Copy Copies another array to the array; grows the array if necessary.

Insertion/Removal
