(1)完成构造函数的定义,把数据成员size初始化为参数s的值,数据成员buffer指向动态申请的int型size大小的空间。请在注释“//**1**”之后添加适当的语句。
(2)完成拷贝构造函数的定义,注意解决多次删除的问题。请在注释“//**2**”之后添加适当的语句。
(3)完成成员函数elem的定义,该函数返回buffer的第ndx个元素的值,注意如果ndx超界,请输出“error in index”。请在注释“//**3**”之后添加适当的语句。
(4)完成析构函数的定义,要求先将字符d打印在屏幕上,再释放buffer指向的空间。请在注释“//**4**”之后添加适当的语句。
输出结果如下:
1234567891012345678910dd
注意:除在指定的位置添加语句外,请不要改动程序中的其他语句。
