If the user enters a negative value for the quantity, tell him/her "invalid quantity". If a zero is entered, tell "Hope you decide to buy our software in the future.

Use the separate paper provided in class to show that you tested your program with your own test cases and tell whether or not your program produced the right result for each test case. Also test your program using the test cases provided in the document named "Assignment 3: runs for software.cpp" and print them out. you Try not to have redundancy in your code. You will lose some points BAR Better way else if...) cout answer is awer else if....) var else if(..........) 3
