All of the work in this project is my own!  I have not left copies of my code in public folders on university computers. I have not given any of this project to others. I will not give any portion of this project to others taking this class. I realize that the penalty for turning in work that is not my own can range from an "F" in the class to dismissal from Trinity University.

Do While Loop

1] Write and study the following block of practice code in main( )

2] Review the do-while loop in your book if you need

3] Remove the practice code from your program.

Main Program Variables

main ()
{
int 
   EmployeeNo;
double
   PayPerHr,
   HoursWorked,
   Gross,        
   Tax,         
   Net;   
char
  Name[30];
       

Pass By Value - Pass By Reference - Textbook

1] If a function does not need to change variables, do not pass by reference!

2] Don't forget to put your prototypes at the top.

3] If you do not feel comfortable with if then else (from class and the example at the top) then look at a couple more examples in your text.

4] If you do not feel comfortable with the do while loop (from the example above) then look at a couple more examples in your text.

Program Documentation Box - Required Of All Programs From Now On!

1] Each and every program, from now on, shall have a main program documentation box at the very top. Do not use any tabs in the documentation box! Make the box 80 characters wide.

Copy File To Dr. Hicks For Grading

1] Copy file tom-hw4.c  to /users/thicks/hw1320/hw4

What To Turn In

1] Signed copy of page 1 of this Lab.

2] Printed copy of the source code.

3] Nothing will be graded until you copy the file into the /users/thicks/hw1320 directory.

4] Nothing will be graded until this lab form is submitted.  Staple the pages. Fold the lab Horizontally (like a hot dog) and write your name nice and large on the outside.  Place it on the professor desk before the beginning of lecture on the day it is due. All assignments are due the next class period unless otherwise designated on the schedule page.
