DOS and UNIX on Windows7

I think a much better solution is to install a virtual pc, such as Virtualbox or VMware Player (both free). They support DOS and UNIX. Any reason why UNIX instead of Linux? If UNIX, are you installing Solaris?

You could for instance pause the execution of your program just before it ends. Just add a pause before the return call in the end. the end of your code could for instance look like this:

Code:

system("pause");
 return 0;
}

Function system("pause") (C++) causes the program to stop until a key is pressed, printing "Press any key to continue" on screen.

Your other question is about Unix. I'm sorry to ask but do you know what Unix is? It is not a programming language. It is not something you can do or practice with Windows. Unix is a computer operating system, some users say The Operating System. Linux for instance are based on Linux.

If you want to learn Unix, you'll find more information here: The UNIX System

Here is a screenshot of a DOS installation on Virtualbox. Just as easy on VMWare Player. Also has option for UNIX, Linux, Windows variants, etc.

Tiny window? Why don't you run VirtualBox guest machine in full screen? For instance following these instructions in installing Linux to VirtualBox you can then use Windows controls to make the windows precisely as big as you wish: Linux - Install on Windows 7 Virtual Machine using VirtualBox

A dual boot Windows / Linux works also well.

First, please keep in your mind this is my subjective opinion, based only on my own experience. Facts can be found on the net and in the library

I have had no speed or other problems in using different Linux distros in VirtualBox, or installing a Windows / Linux dual boot. I guess it's partly because I'll always try to do things, especially when I'm doing it first time ever, exactly as I've been told and / or how the manual or instructions say it should be done. I mean, no shortcuts or "that must not be important, I'll just ignore that" attitude. Like everything else in computing, the principle is easy: If your system is well maintained and you follow the instructions, it usually works.

If the Guest Additions are installed, RAM & Video RAM memory settings correct, there should be no speed problems. In any case you are not using a virtual machine to play GFX intensive multiplayer online games or to edit HD video.

If dual boot is more your thing, I recommend using BIOS to choose which OS to boot, if your system is up to it. If you use traditional bootloader, my recommendation is and has always been to install Windows first, and let Linux handle bootloader.

This is why I prefer virtual machines whenever possible.

First, my windows 7 dual display system. Main display on the right reserved for Windows, left having Solaris Unix in full screen mode. With VirtualBox Guest Additions mouse totally integrated, moving without restrictions from one OS to next, keyboard working on any active app or window, regardless of which OS it belongs. Cross OS copy & paste and share of course working:



And then even better, Solaris running on left display in so called seamless mode, i.e. desktop is integrated to Windows desktop, shared with it. For instance in this screenshot on left display there's a Windows Explorer window together with Solaris File Browser and Solaris Mozilla net browser. Solaris taskbar and Launch menu ("Start Menu") on left display, Windows Taskbar and Start menu on right display:



I just love to use PC like this!
