Chapter 10, Problem 8SA

Consider the definition of the following class: (1, 2, 3, 5, 7)

$\begin{array}{l}\text{classproductType //Line 1}\hfill \\ \text{{ //Line 2}\hfill \\ \text{public: //Line 3}\hfill \\ \text{productType(); //Line 4}\hfill \\ \text{productType}\left(\text{int, double, double}\right)\text{; //Line 5}\hfill \\ \text{productType(string, int, double, double);//Line 6}\hfill \\ \text{productType(string, string, string,}\hfill \\ \text{int, double, double); //Line 7}\hfill \\ \text{voidset(string, string, string, int,}\hfill \\ \text{double, double); //Line 8}\hfill \\ \text{voidprint()const; //Line 9}\hfill \\ \text{voidsetQuantitiesInStock(intx); //Line 10}\hfill \end{array}$

$\begin{array}{l}\text{void updateQuantitiesInStock (int x); //Line11}\hfill \\ \text{int getQuantitiesInStock () const; //Line12}\hfill \\ \text{void setPrice (doublex); //Line13}\hfill \\ \text{doublegetPrice()const; //Line14}\hfill \\ \text{voidsetDiscount(doubled); //Line15}\hfill \\ \text{doublegetDiscount()const; //Line16}\hfill \\ \text{private: //Line17}\hfill \\ \text{string productName; //Line18}\hfill \\ \text{string id; //Line19}\hfill \\ \text{string manufacturer; //Line20}\hfill \\ \text{int quantitiesInStock; //Line21}\hfill \\ \text{double price; //Line22}\hfill \\ \text{double discount; //Line23}\hfill \\ \text{}; //Line24}\hfill \end{array}$

1. Give the line number containing the constructor that is executed in each of the following declarations.

   $\begin{array}{l}\text{i}\text{. productType productl;}\hfill \\ \text{ii}\text{. productType product2 ( "Microwave" , "M3562",}\hfill \\ \text{"GeneralPool", 35, 175}\text{.00, 0}\text{.1);}\hfill \\ \text{iii}\text{. productType product3 }\left(\text{"D1290", 25, 375}\text{.00, 0}\text{.05}\right)\text{;}\hfill \\ \text{iv}\text{. productType product4}\left(\text{10, 8}\text{.50, 0}\text{.2}\right)\text{;}\hfill \end{array}$

2. Write the definition of the constructor in Line 4 so that the instance variables are initialized to “ “, “ “, “ “, 0, 0.0, and 0.0, respectively.

3. Write the definition of the constructor in Line 5 so that the string instance variables are initialized to””, and the other instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.

4. Write the definition of the constructor in Line 6 so that the instance variables productName and manufacturer are initialized to the empty string, instance variable id is initialized according to the first parameter, and the remaining instance variables are initialized according to the last three parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.

5. Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.
