Please help

1. Write a program reading input from the user. I do not particularly care how (via a file, or making them type something in, or a command line argument via argc/argv). What this program does is up to you, but it should use a variety of features of C++ discussed in Chapters 1-3. For each first appearance of a feature, document where in Chapter 1-3 it is introduced in the textbook (section or page #). You should use at least a couple of features from each chapter. The program should have at least 300 lines of code, as measured by cloc, and it should only require standard C++ libraries, no unusual packages -- the code should compile and run as-is easily on Mac and linux platforms.

2. The program should do something interesting; again, what is really up to you, but you should be able to explain the purpose of the computation in a comment at the top!

3. You'll want to prepare a second version of the program that _is broken_. You should introduce a bug into the program so that for some (but not all!) user inputs, the program does _not_ do what it should. This should be a matter of incorrect use of C++ language features, not something very obvious on inspection. That is, don't write things like: if (input == bad_value) { go_haywire(); } instead have the bad values somehow cause issues, perhaps by omitting a check for valid input that is in your first version of the code.

4. What you submit is a pdf report with both source code versions and an explanation of what your program does, what the bug is, what language feature it mis-uses, and how hard you think it would be to detect the bug. The report should be at least 1000 words, not counting the code listings.

Chapters 1-3 are about C++ Fundamental Data Types, Decisions like if statements, and Loops.

The book these chapters are from is Big C++: 3rd edition by Cay S. Horstmann
