给Vector类添加insert

Object objects[theCapacity];
iterator insert(int pos,const Object& x)
{

    Object* oldArray=objects;
    theSize++;
    int i=0;
    if(theCapacity<theSize)
        theCapacity=theSize;
    objects=new Object[theCapacity];
    while(i!=pos)
    {
        objects[i]= oldArray[i];

        i++;
    }
    objects[pos]=x;
    for(int k=pos;k<theSize;k++)
        objects[k+1]=oldArray[k];
    delete[] oldArray;
    return &objects[pos];
}
