Follow the instructions for starting C++ and viewing the ModifyThis18.cpp file, which is contained in either the Cpp8\Chap12\ModifyThis18 Project folder or the Cpp8\Chap12 folder. (Depending on your C++ development tool, you may need to open the project/ solution file first.) The file contains the code shown earlier in Figure 12-8. The first column in the array contains the sales amounts for paperback books sold in each of the three stores; the second column contains the sales amounts for hardcover books. Jenko Booksellers has opened another store. The store’s sales of paperback and hardcover books are $1650.85 and $1246.85, respectively. Add the new sales information to the array, and then modify the program appropriately. Save and then run the program.
