1.     Variable Naming Conventions. Explain whether each of the following is a valid variable name.

if that even makes sence can some person who knows what he or she is doing help me out

I find it very difficult to believe that the student has a homework assignment consisting of looking something up on the internet, especially if it's about the syntactical details of a computer language he's not actually studying.
And even if it were his assignment...that's still no reason not to do it himself.
Anyway, in computer programming, spelling mistakes KILL. So that's why we make fun of your spelling mistakes. It's better that you learn here than when your nuclear reactor control program fails.

  • I can not open any programs on Firefox that I installed on my other computer after restoring that computer.

    I have been a Firefox user for as long as I can remember and do not remember having such problems until I insttaled 34.0.5 I have mostly used Google as my search engine, and sometimes yahoo.
    Everytime I try to open say yahoo or google to install them along with many other sites First ir goes to yahoo search instade of google search as I have set as my search engine. I don't like the fact that I no longer have the choice on which search engine I want by default. Nor can I see any means of removing all the others listed Vosteron, that is the first probelem.
    I seach for yahoo.com, so I can install it back on the computer, and get this error or alert message with a yellow box in the top left with a crossing guard figue. It says This Connection Is Untrusted. I get it over and over and over, on any sites I have tried opening over the past three days.
    I don't know what to do, I've tried about:config and resetting the SSL from 2 to 1. I still get the This Connection is Untrusted. Even tried to add a exception, but it still gives me that annoying message. At this point I do not know it I have some kind of malware, or what. But I have not put many programs back on the computer sense I restored Win 7 onto a new hard drive.
    I hope you can help me get this annoying problem fixed once and for all. Otherwise, it Safary.

    Reset Firefox to its default state
    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.

    I hope you can help me.  I purchased adobe captivate 8 on line and when I click on the email link to download, it comes up with 7 programs, some are 64 bit and some are not, my computer is 32 bit.  I am not sure which of these 7 to download?  All or just the 4 non 64 bit?

    I tracked down the problem with the download and installation, my windows 7 was missing a file and after reinstalling windows everything worked out.  The first 32 bit program in their list was used.  I hope this can help others.

  • The letters and numbers are not forming properly, do I have an compatibility issue? Is there an adjustment for this? My computer programs and explorer are ok.

    If i move the curser over the letters or numbers they snap up bright. In about 30 seconds they go back to the blurry state. This only happens on Firefox. not explorer or my regular computer programs.

    Hello,
    First you have two Shockwave Flash and Adobe Shockwave for Director Netscape installed in your computer:
    *Shockwave Flash 12.0 r0
    *Shockwave Flash 11.8 r800
    *Adobe PDF Plug-In For Firefox and Netscape 11.0.06
    *Adobe Shockwave for Director Netscape plug-in, version 11.5
    So, try disable the hardwareacceleration:
    Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
    You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
    Then perform these steps:
    *Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
    *In the Firefox options window click the ''Advanced'' tab, then select "General".
    *In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
    *Now, restart Firefox and see if the problems persist.
    Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
    * [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
    * [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]

    the problem I have since I upgraded to Mavericks version 10.9.1
    The problem appears only with Mail not with other programs, not even with my browser.
    When I try to zoom the text of an e-mail I received or sent , I can no longer use the keys Command + to enlarge the text, although I can reduce it with Command -.
    As I have a problem with my eyes, This is a serious matter for me.
    When I write an e-mail, if I select text and press Command +, it just displaces the text to the right.
    Now, my husband has a USB keyboard. If he connects it to my computer, his regular Command + does not work either, but  he uses the extended keyboard, then it works. Unfortunately, he needs it for a musical application which does not work with a wireless keyboard.

    Firefox 3.6.4 and 3.6.6 use a process called, "plugin-container.exe" which was using up most of my CPU when I opened up multiple tabs that contained Adobe Flash files, and caused Firefox to lock up.
    My solution was to use Firefox 3.5.10 which you can get from the Mozilla website at [http://www.mozilla.com/en-US/firefox/all-older.html]
    I am using Adobe Flash 10.1.53.64 without any problem in this version of Firefox. Check the release notes, I believe it contains all the latest security fixes in "Firefox 3.6.4".
    Hopefully, they will fix Firefox 3.6 in the next version (e.g. Firefox 3.6.7), until then you should probably use "Firefox 3.5.10".

  • How do i sell a macbook using Apple's refurbished computer program.

    I have an intel core duo MacBook with 2GB of ram and a 120GB hard drive. (it also has a superdrive).
    How do I sell this on Apple's refurbished computer program and how much do you think that I would get for this computer.
    Thanks.
    MACBOOK   Mac OS X (10.4.7)  

    I've sold one Macbook and two minis on ebay with no problem. I always use Paypal and only ship to a Paypal verified address. On each sale I got just about what I paid for the macs minus Paypals cut. Selling to a live person for cash may sound good but you're letting someone know you have an expensive laptop at your home and that might bring the wrong person. I have sold on eBay for several years (feedback 300+) and have never been scammed. People try of course, you always get the emails asking where you are and can they come by. Or you get the offer to buy your laptop for $500 more than it's worth IF you send them the laptop via their fedex account and they pay on receipt. NOT! If you sell on eBay use Paypal and ship to verified address sellers are covered too for problems with sales. Good luck in selling your Mac you should get a good price.

  • Error: could not open `C:\Program Files\Java\j2re1.4.0_01\lib\i386\jvm.cfg'

    I am geting this error when I enter the "java" command:
    "Error: could not open `C:\Program Files\Java\j2re1.4.0_01\lib\i386\jvm.cfg'"
    I have configured the PATH variable (Windows 2000) and "javac" works. I cannot, however, get my programs to run because of the error every time I type "java". Also, I did not install my JDK / SDK to the directory in which the computer is looking for the "java" cammand (ie. it is not in 'Program Files'...). If anyone can help, it would be greatly appreciated. Thank you.

    Try using the -cp switch on the command line. For example:java -cp . MyProgramIf this corrects the problem, you need to set the classpath variable
    as well as the path.

  • Why will my photoshop elements icon not start the program??

    I just downloaded photoshop elements, and it worked fine for the first 2 days. However, whenever I try to open photoshop now the program will not open! It says "do you want to run this file?" and I clicked "Yes" but then nothing happens! At the most the welcome page will pop up and I am able to open Elements organizer, but not photoshop! I have tried uninstalling and re-installing the program and everything else the support page suggests. Anyone have experience with this problem?

    I'm not real computer literate. Might you know where'd I would find it?  There are 5 disks in the softwear, the first 3 are install files dependent on what Windows program is loaded. The last two say Content.   Thanks for your help!

  • Macbook not opening certain programs and running others slowly.

I also can't access the other account on my computer. I downloaded virus protection and ran that, but my computer is still not working right! What should I do? Any help would be greatly appreciated!

  • AP Computer Programming Practice Exam

    I am in Advanced Placement Computer Programming 12, a High school Java Class. My teacher is actually the AIT teacher, and the visual basic teacher, and does not seem to know much about Java since he cannot answer most of my questions. I was given a textbook and told to learn, because the teacher teaches us and the normal Computer Programming students (Visual Basic) at the same time, and they are more important. However, we do pass in assignments to him.
    He has been marking me down for forgetting the date in the comments, for forgetting to name my variables with a type (double dblVarName, instead of my way, varName), not enough whitespace, etc. Is this even allowed? It is not in the textbook. I should also mention I have been programming for 4 years and I know 16 languages including C++, but my specialty is PHP, so I code WAY differently then him, and lose points because of my style.
    All of my programs to work EXACTLY as the book shows they should. I do an exam for him and the official college level exam, so i don't know what to do. I should also mention that half of the people have failed HIS exam in the last 4 years, and all of them except 2 have failed the College Level Exam. My Physics teacher who is a programmer told me to download the practice exam for the College Level one, so I was wondering where to find it, any ideas?

You're going to have to please someone with your coding style no matter what you do.
    It is not in the textbook. I should also mention I have been programming for 4 years...Congratulations, before I went to college I had programmed for at least that long and so had most of the people I was in college with.
    and I know 16 languages including C++, but my specialty is PHP, ...in something like 8 different languages not including various dialects of assemblers... and that was back in the day before dinosaurs roamed the earth (before the internet and these things they call scripting languages).
    so I code WAY differently then him, and lose points because of my style. Get over it and learn to do it the way the shop wants. It just sounds in this case both of you have a rather large case of themselves. You are going to be required to accept some standards in your programming career--even in college there is some discretionary points given for style--yes, white space, variable naming, the number of lines in your code, readability and etc. (I'm not saying he has the end all of styles or what he is requiring is correct, but he is the one you have to please right now with your style--it rather foolish not to--he's the one with the grade book.)
    Getting a program to work it only part of the desired result, it's about time you learned that. You have to be able to cut easily readable, easily maintainable, highly cohesive, correct code. Yes, pretty print actually counts in the real world too. Decide to do it right now and you'll be a lot better off later on.
    When you get to college you're going to find one thing: everyone is going to be the top of their class... AP placement... programmed for X years... knows XX languages... etc. You're finding that just getting it to work is not the end all of the problem. DO IT RIGHT, and learn what your instructor is trying to teach you... get some style that you can be proud to show in a job interview instead of what you are doing now.
    BTW: I had a very similar attitude going into college, and shock of my life... everyone was the top of their HS programming classes. This was driving home to me in my Senior year in a Systems Programming class that was taught by the CS Department Chair. He stood up in front of the class and faced us very solumn faced and sternly asked: "Who here thinks they are gifted?"
    I raised my hand and he looked at the others and siad: "What's the matter with the rest of you? You are the top 2%, if you're not gifted who is?"

    Long time ago I trialed Elements 9  and could not remove from Programs at the time; still can't?
    I didn't go forward with '9' because of its size and it didn't appear to provide advantages for the cost.
    How do I uninstall it when conventional methods fail. Message received in Windows Installer is, ' The feature you are trying to use is on a network resource that is unavailable.' Elements 9 cannot be used.

    " When I did this, my library showed all the music I have "purchased" from itunes but did not have the music that I downloaded a long time ago through itunes from my old CDs."
    Correct.
    " How can I get that music to show up in my library now on my new computer?  "
    Copy it from your old computer or your backup copy of your old computer.
    The sync is one way - computer to ipod.
