vector实现
求自己实现的vector类，作业...源代码看不懂.. 有没有简单点的..
[解决办法]

template<typename T>
class Vector
{
public:
    typedef T* Iterator;
 
    Vector()
    {
        cnt = 0;
        arr = new T[100];
    }
    ~Vector()
    {
        delete []arr;
    }
    Iterator Begin()
    {
        return &arr[0];
    }
 
    Iterator End()
    {
        return &arr[cnt];
    }
 
    void Push_Back(T v)
    {
        if(cnt >= 100 )
        {
            std::cout << "Vecror容量已满，不可再插入。" << std::endl;
            return;
        }
        arr[cnt] = v;
        cnt++;
    }
    T operator[](int i)
    {//[] 下标
        return arr[i];
    }
private:
    int cnt;
    T *arr;
};
 
int main()
{
    //char*
    Vector <char*>vecc;
    for(int i = 0; i < 4; i++)
    {
        vecc.Push_Back("A");
    }
    for (Vector <char*>::Iterator it = vecc.Begin(); it != vecc.End(); it++)
    {
        std::cout << *it << std::endl;
    }
    return 0;
}
