构建一个类 Stock，含字符数组 stockcode[]及整型数据成员quan、双精度型数据成员 price。构造函数含3个参数:字符数组na[]及q、p。当定义 Stock的类对象时，将对象的第1个字符串参数赋给数据成员 stockcode，第2和第3个参数分别赋给quan、price。未设置第2和第3个参数时，quan的值为1000, price的值为8.98。成员函数 print没有形参，需使用this指针，显示对象数据成员的内容。假设类 Stock第1个对象的3个参数分别为:＂600001"、3000和5.67，第2个对象的第1个数据成员的值是＂600001"，第2和第3个数据成员的值取默认值。
Build a class stock, including character array stockcode [] and integer data member Quan, double precision data member price. The constructor has three parameters: character array Na [] and Q, P. When defining the class object of stock, the first string parameter of the object is assigned to the data member stockcode, and the second and third parameters are assigned to Quan and price respectively. When the second and third parameters are not set, the value of Quan is 1000, and the value of price is 8.98. The member function print has no formal parameters. You need to use this pointer to display the contents of the object data members. Suppose that the three parameters of the first object of the stock class are "600001", "3000" and "5.67", the value of the first data member of the second object is "600001", and the value of the second and third data members is the default value.
