- the character to express special character (ex. \\ : express the special character '\'(backslash))
- separate directory in 'Windows API' (c:\work\test.dat)
(In Windows programming, you have to write down like this c:\\work\\test.dat. Because \(backslash) is a special character)
(In Windows programming, you can also use /(slash) "c:/work/test.dat")

*'/' : slash
- separate directory in 'Linux' or 'Windows Programming'
- comment in Windows Programming (ex. // : Don't extract this line)


< Ubuntu(Linux) >

In that category, you can set the internet with the same method of windows.

1. Download the program file 'Wubi' at the  http://www.ubuntu.com/.
(tips) Wubi is the program which can be used on Windows Environment.

2. Install the 'Wubi' program in your windows OS.
(tips) You can handle the 'Wubi' as an application program, even though 'Ubuntu' is a operating system.
(tips) You may cannot know whether the 'Wubi' is 32bit version or 64bit version. After installation you have to confirm the version. I couldn't find the information in Ubuntu. I just could know by installation of Ubuntu application programs. When I download 32bit version program, that program didn't work. ^^; If you know the method to check the version of 'Wubi', please let me know that.
(tips) When I was installing the program, I encountered the message about the problem of GNOME file. I neglected the message, and now I don't have any problem.
(tips) It takes so long time, so you would be better to install when you don't have to use the computer.

3. After installation, reboot your computer then you can see the menu to select the OS. Now, you can use the Ubuntu OS. ^^
