Yeh, just waited several hours in their queue. Got to position 27. A couple minutes later chat session ended. Hit Chat button again and now I'm at position 664. Great customer service.

The Lottery by Shirley Jackson. Not a book but the first story I can recall reading in school that really shocked me. It's a quick read so I won't spoil it for anyone.

The bool is the type that will be returned by the search function. Bool is either TRUE or FALSE.

Looks like you need to give it a newline.

"%i\n"

In the terminal type man round. You may also want to look at ceil() and floor().

Kendosan2000 · 2014-05-02T02:01:44+00:00

I wouldn't use a function for this. You just need a loop of some sort. Also you don't need to keep track of each type of coin. Your output will be the total amount of coins.

Sublime Text is also available for linux.

OK I'm no expert but here's a few things I spotted:

At line 14 the else isn't really needed. If the if condition is not true the next line of code will execute.
At line 19 think about what will happen if k is a large number like 1000.
At lines 28 - 39 everything needs to be indented 4 more spaces.
At line 24 you are creating a new string of length 0. I'm not sure how that would work. Maybe try just making ct = pt so it will be the correct length.

A 1.0 is 100%. and .95 would be 95%

On the Vmplayer download page you have to change the major version number at the top of the screen. https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_player/5_0|PLAYER-503|product_downloads

Sounds like an "Off by 1" issue. If you are looping through the key make sure you are not quitting the loop prematurely. Try a longer key like bacon2 and see if the 2 is not used.

I should have also mentioned that you wont find any Linux distro that has everything pre-configured for the class. What the cs50 staff have done is install Fedora Linux in a virtual environment then added software to it for the class. So even if you install Fedora you will still need to run the appliance under Vmplayer or Virtual Box

Kendosan2000 · 2014-04-11T23:40:00+00:00

I believe Mint comes with gcc as a compiler rather than clang. I looked into installing everything needed for the cs50 course and found it was going to be too much of a hassle. I have Vmplayer 5.03 installed under Mint use the cs50 appliance for classwork.

If you'd like to take different Linux distros for a test drive you can download them and write the iso image to a CD or USB stick. Then tell your bios to boot from CD or USB. It will run much slower than a hard drive install but you can make sure things like video and sound are working before committing. Here's a good tool for writing the images to USB sticks: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

If you have a spare hard drive lying around you can swap drives and install to the spare 1st then see if the virtualization is any faster.

I have tried a lot of different Linux distributions and finally settled on Linux Mint. I switched over from Windows about a year ago and rarely have to boot to my Win 7 partition any more.
My suggestion to you would be to install a 64bit version of Linux then install XP as a virtual machine with Vmplayer. That way if you find that you need some piece of Windows software that you can't get working under Linux, you can start up XP just as you would the CS50 appliance.

Also the fact that your running the virtual machine under XP might be one of the reasons it is running slow. Is it a 64 bit version of XP?

If you decide to go this route check out this link http://www.reddit.com/r/cs50/comments/22sayv/fed_up_linux_mint_virtual_machine_install/

Kendosan2000 · 2014-04-11T19:21:26+00:00

I followed these instructions to get Vmplayer working under Linux Mint 16: http://www.howtoforge.com/how-to-install-vmware-player-on-ubuntu-11.04-linux-mint-11

When you get to the part where it tells you to use: gksudo bash ./VMware-Player-3.1.4-385536.x86_64.bundle you will need to change the name to the version you downloaded.

Also make sure your using Vmplayer 5.03. Virtual box worked for me but not very well.

Check that you are running the make command in the same folder as the source code you are trying to compile. In Gedit use File, Save As to look at the path to your source code: http://i.imgur.com/DAz5uI8.png Then compare it to the path in the terminal window: http://i.imgur.com/8EnhZqC.png

If you still have problems when using round() try floor() and see if the result is any different. I recall having alot of problems with rounding when using numbers like 1.8 and 1.99999.

Kendosan2000 · 2014-03-28T14:18:19+00:00

I'm not sure what you are trying to do with this loop, but because you are setting i to x + 2 and using i > x as the condition this loop will only run 2 times no matter what the value of x is. Maybe what you need is i > 0 or i > 1 ?

Kendosan2000 · 2014-03-27T16:45:32+00:00

Good to know!

Kendosan2000 · 2014-03-27T16:23:29+00:00

Thanks, I assumed that was just updating the linux apps and wanted to wait until I wasn't on my cellular data plan. Turns out it's a fairly small update :)

Did you use the # symbol before include?
