Open and close files only if the user selects file input and the files were opened

None of the implementations in requirements $1$ through $6$ can be used more than once $($e$.$g$.,$ you

cannot compute leap year more than once, you cannot have two if$/$else$-$if statements assigning

month name, etc.

Program Documentation & Style

Declare all variables and constants that your program uses at the beginning of your program.

Your program should include two types of comments:

Header Comments at the top, including lines with:

a$)$ Your name, course name, and class time

b$)$ Program assignment number, program file name, and the due date

c$)$ A sentence or two explaining the purpose of the program

d$)$ A description of the input data needed by the program when you run it

e$)$ A description of the processing $($calculations$)$ done by the program

f$)$ A description of the results $($output$)$ produced by the program

g$)$ A reflection on your assignment $($see example header below$)$

$//$ Program: Explain the purpose of the program

$//$ Process: Describe hon the program computes the solution.

$//$ Results: What are the caleulated results?

$\frac{\frac{?}{?}}{?}$

$\frac{\frac{?}{?}}{?}$ Class: $cs2010$

$//$ Section: $100$x

$//$ Term: Spring$/$Ta$11202$x

$//$ Author: Student's name

$\frac{\frac{?}{?}}{?}$

$//$ Reflection: Enter your reflection here. It in worth $1$ point on the rubrie.

In$-$line comments: There should be an in$-$line comment for each primary step in your program. In general, this means a

comment with each group of $C++$ statements that handle the declarations, input, processing, and output steps of your

program

Use meaningful identifier names

Include clear prompts for the user about entering the data

Include clear descriptions of the results when you display them

Format output neatly

Turn$-$in Instructions

Always ensure your project is closed before making a copy or preparing for submission. From the File menu in Visual

Studio, select Close Solution. If a dialog box asks if you want to "Save changes to the following items," click the Yes

button to save any changes you have made to your project before it is closed. $($DO NOT use Save As$.)$

Locate your project folder $($e$.$g$.,$ AfflackB$\_$Pgml$)$ on the Desktop or wherever you have saved it$.$ You will submit only the

$.$cpp source file $($e$.$g$.,$ AfflackB$\_$Pgm$1.$cpp$)$ on Canvas.
