I'm having a problem with getting this code to print out to file due to some undefined behavior. It seems that when I test it the output file opened but was empty. can anyone run it on their system and tell me if it work on your system or is it not working at all. Also can you provide me with the output file if you run it.
here is the code

and the data for the file

thanks
Per the code comments:
The compiler is supposed to be gcc, the system("PAUSE") won't "work" in most UNIXes. It looks like it is meant to be compiled under cygwin running on a Windows PC, or under Linux. Not Windows. The PAUSE part makes very little sense, since that is largely a DOS command. You had to have copied the code from someone, it looks like the code scores competing ice skaters. The probability that it is production code is low.
Where did you get the code, and what assignment is this supposed to be for?
Suggestion:
See www.cygwin.com to install cygwin on your PC.

I am very new to programming and I need to write a program that takes an assembly-language program and produces the corresponding machine language.
I need to write the program in C
Does anyone know any good tutorials I can find to create this program?
What you would want to do is finding a datasheet which describes the different op codes for the assembly instructions you're writing. Try ISA "your processor name" - this might come up with something useful.
It probably will be hard and you will run into a lot of problems, but you'll probably learn something from it.

I am having trouble with executing my executable file by executing my program from the location of the program. I am using eclipse, and when I paste the location of my executable file from debug in eclipse, onto the command prompt my program works perfectly. However when I try to execute my program from the location of the debug, my program is altered, any help please?
After it begins to execute, is your program using relative paths to input files that might be different?
Are you an administrator on the computer and/or running eclipse as administrator? You could try running the command prompt as administrator to confirm that it isn't a permissions issue.
You can't work it in the debug. Because the program is working in the normal directory. Simply work in normal directory and its fine.

I have a project I'm going to be doing on a microcontroller. I plan on having it interface with my computer over a USB serial connection. I tried doing the basic tests like putc(getc()), but I'm having trouble getting it to behave as I expect.
With that simple hardware-echo thing, many things just don't work. When I push enter, I just get a carriage return. Backspace does nothing. CTRL-C for breaking doesn't work either.
I'm using GNU Screen as my terminal emulator. How do I learn how to handle all of this(along with stty settings) so I can make a useful command interface on my microcontroller?
You will need to know what terminal type your Screen terminal is emulating so that you know what codes to send out the serial port. For example, if you set your terminal to VT100, you can check out this link which provides some VT100 codes
And for gnu-screen you might want to check this out as it contains an exhaustive list of ESC and control strings/commands that you can use.

I have practically no experience with programming outside of ide's (Microsoft Visual Studio, netbeans and eclipse) and I am beginning to learn C programming. I have adequate experience with C++ and Java. I have downloaded gVim 7.3 and am looking for some guidance on how to program in C with vim. I do not even know where to type code with vim! I am completely lost and am looking for instructions to run simple command-line programs such as hello-world (to start). Also, would notepad++ be of any use?
Somebody please show me the world of C programming and Vim
Usually its done like this - you open up a shell window, set your compile enviroment configuration. Then open any files you are working on with gvim to have a C syntax highlighting available, modify them and save. Get back to shell window repeat make command or whatever you need to compile and link application.
The usefull extension for me was ctags, which allows to browse declarations. You dont get the comfort of code completions, intelissence, on-the-fly error messages or list of function parameters, but I didnt miss that much eitherway.

I would consider myself a fairly competent programmer with experience in Java and VB.net. My latest swim around the programming lake is having me modify a program written in C. (The program is Wireshark, an open source network analyzing tool.) I followed the instructions here http://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin32.html and simply don't know where to go from there. I'd like to use Visual Studio 2008 to work with the code if possible, but will do whatever is necessary. (I'm a total noob at using command prompt to do anything though.)
If you followed those steps, then you've built it. I'll copy Section 2.2.10 here.
2.2.10. Build Wireshark
Now it's time to build Wireshark ...
If you've closed cmd.exe in the meantime, prepare cmd.exe again
nmake -f Makefile.nmake all to build Wireshark
wait for Wireshark to compile - this may take a while!
run C:\wireshark\wireshark-gtk2\wireshark.exe and check if it starts
Just make changes in the code, do these steps over again, and presto! you've modified the program. You may want to bone up on C debuggers if you're doing anything very complicated.
