听力原文： The wage gap is a statistical indicator often used as an index of the status of women's earnings relative to men's. It is also used to compare the earnings of other races and ethnicities to those of white males, a group generally not subject to race—or sex—based discrimination. The wage gap is expressed as a percentage(e.g., in 2003, women earned 76% as much as men) and is calculated by dividing the median annual earnings for women by the median annum earnings for men.
The Equal Pay Act was signed in 1963, making it illegal for employers to pay unequal wages to men and women who hold the same job and do the same work. At the time of the EPA's passage, women earned just 58 cents for every dollar earned by men. By 2003, 40 years later, that rate had only increased to 76 cents, an improvement of less than half a penny a year. Minority women fare the worst. African-American women earn just 65 cents to every dollar earned by white men, and for Hispanic women that figure drops to merely 54 cents per dollar.
If working women earned the same as men(those who work the same number of hours; have the same education, age, and union status; and live in the same region of the country), their annual family incomes would rise by $4,000 and poverty rates would be cut in half.

(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。
