Lab 4
Due Wednesday, September 18

Casting a double to a long

Begin this lab by downloading the following files:

lab4_main.c: Main file for the program

Detailed instructions

Log on to one of the computers in the lab.
Open up a terminal
Go to the directory where you started your program 2, and download the new main function into that folder.

To compile this program type:

gcc lab4_main.c convert.c -Wall -o lab4 -std=c99

When you are done, submit your source file. In order to submit your file, you will need to be SSH'd in to agate.
```
~cs520/bin/DoSubmission.py lab3 convert.c
```
I will use my own copy of the main function, and the header file, so if you do modify those, your modifications will not be used when grading your program. For this lab, I will not be doing other tests on your program. If your program passes all of the tests in the supplied main file, you will get a perfect score on the execution portion of this assignment. Note you will still be required to submit good looking code.

Submitting

Please submit whatever you have at the end of lab, even if it is incomplete. You have the rest of today to finish this assignment.

Grading

Your program will be graded primarily by testing it for correct functionality.

I am giving you a main file that does some simple tests with your program. 100 points will be awarded for passing the simple tests associated with the testing main file that I give you.
Do not return the result of a cast, or you will receive a 0.

In addition, remember, you may lose points if your program is not properly structured or adequately documented. Coding guidelines are given on the course overview webpage.

Next Steps

Some students may have finished the work for this lab already. For those students, I would encourage you to work on converting larger floating point numbers, and handling overflow situations.
