How to run Turbo C++ in Windows 7 in full Screen.

This tutorial will guide you how to run Turbo C++ in Windows 7 or Windows Vista (and other 64-bit Windows OS) in full screen mode.
Note: We have transferred to new domain to cover all tech stuff. Visit: www.techgoblet.com . This tutorial is available here
Command being 16-bit application doesn’t allow itself to run in full-screen mode in these Operating System. Whenever tried, one will be greeted with the image shown.
Same goes with Turbo C++ (tc.exe). It is also command originated and thus, will not let you work on full screen mode. There are some unexpected crashes which one may have to endure.
In order to aid, we will use a 32-bit emulator application called as DosBox.
- If you haven’t grabbed Turbo C++ setup, download it from here.
- Create a new folder in your C: and rename it to ‘turbo’ [or anyone you feel like]. Reason for doing it will be mentioned as you read.
Now, run the installed setup file [TC3setup.exe] and give the extraction position as 
- Now, download the DosBox setup from here
- Install DosBox in your system.
- Now run DosBox. A command prompt type window will appear. Now note that there is a difference between the command prompt our system is equipped with and this version of command prompt. This emulator is 32-bit in contrary to native 16-bit prompt, therefore, allowing you to run it in full screen mode.
- In this window, we now need to mount the folder via this command:
This tells about the reason behind creating another directory while extracting TC3setup.exe. Mounting works relative to a folder, here Turbo. - Work is almost done. Now, type “C:” to mount above mounted drive.
To list the content of this mounted space, type ‘dir’
- Type
>cd tc
>cd binto reach within subdirectories for tc.exe
Now type tc and press Enter.
Press Alt + Enter to go in Full Screen Mode.
This task may look all so tedious. But, everything can be automated in a single go.
Once you have successfully managed to run it in full screen mode, you can easily automate the process by editing configuration file. You can drop comments below in case of any problem to get through.
To run TC automatically on running DosBox:
Search for “DosBox” in start menu.
Now click on DosBox 0.74 Options
A configuration file in Notepad will be opened.
Go till the end of the document and add following lines there:
mount c c:\turbo
c:
cd tc/bin
tc
Save this file and exit from notepad.
Run DosBox again. Voilla! It will take you straight to TuboC++.

i had install dosbox…and now it works on full screen also…..bt there is 1 problem when i run my program it shows error of libraries and evn fatal error ,bt i whn i used to do same work in a small window without any help of dosbox it runs correctly….. so do tell me in dosbox why it is not running properly?????/
June 11, 2011 at 8:35 pm
@Shubina; That can be solved easily. I explained that above. Turbo C requires relative path for running it. It means, that you need to mount your directory of tc in dosbox in such a way that you are able to access it as : C:\tc\bin\tc.exe .
You must have been using the format as : C:\bin\tc.exe.
So, just create another folder (say, “new”) and extract tc folder in it.
Then “mount new”
After it, it is fairly easy.
C:
cd tc\bin\
tc.exe
Solved!

my program doesn’t run when i press ctrl+F9…
plz help me to run my program…..!!!!!!!!!
June 17, 2011 at 1:16 am
Ctrl + F9 is the shortcut to terminate DosBox application. So, instead of compiling your program, it quits it.
To ‘Compile & Run’. Press Alt + R to go in Run Menu. Then, choose ‘Run’ to perform that function.
Also, Ctrl + F9 can though be assigned to perform that function for you but, you will not wish to get into it’s details. 
. Do let me know if you do.

July 31, 2011 at 12:45 pm
Upload TC folder in C:\new
use this command in DosBox:
mount c c:\new
Then type- C:
cd tc\bin
tc

August 25, 2011 at 1:31 pm
the alt+enter is not working bro…. T_T
August 26, 2011 at 3:55 pm
It will work. Try another combination of Left/Right Alt key + Enter. If it still doesn’t work, then right click the title bar of Dosbox window and go in ‘Properties’. An option for Full Screen must be present there.
Good Luck.
October 8, 2011 at 9:06 pm
I have also the same problem. Tried both combination of Alt + Enter. The result is same, i.e., hanged full screen. Right clicking Title box of Dosbox does not give any “Properties” tag.
I am using Win 7 Pro 32 bit. Please help me with some other option.
January 2, 2012 at 4:03 pm
same here bro, when i press alt+enter, blank black screen appears. help me.
January 2, 2012 at 7:24 pm
You sure that TC worked normally in unmaximized screen? Make sure that you followed all the steps mentioned above correctly and try again.
Good luck.
August 27, 2011 at 5:04 pm
turbo C is run in dosbox but it is not save program in folder
September 9, 2011 at 11:51 am
It does. Just check the relative position where you are ‘actually’ storing your programs. Good luck .

hiii bro
i have a problem in running c++ in windows 7
after typing cd tc
it will give a message unable to open tc
plz help me
September 9, 2011 at 11:50 am
Probably you are mounting wrong folder. Do one thing. Before typing cd tc command, type dir
This command will list all directories present. Then use cd command and directory-result(which popped in by dir command) to go in that directory.

Is TC working perfectly fine before you press Alt+Enter? Please note that it should, otherwise, you unfollowed some step somewhere.

thank you! but how can I get out from a running/error program? and the window isn’t the same like if we run turbo c by cmd.
October 29, 2011 at 3:27 pm
Try pressing Ctrl + Break to break out. Send screenshot to me at allnewankur[at]gmail[dot]com . I think it must work perfectly fine. It does.

Because the name of the file is not ‘garphics.h’; it is ‘graphics. h’.

November 2, 2011 at 6:49 pm
Don’t use Ctrl+F9 to run the program. Either do it manually or use Alt Shortcut to go to menu first and navigate to Run.

November 28, 2011 at 11:19 pm
Are you sure you followed the instructions correctly? I specially specified to strictly follow the directory pattern.
Do cross-check it, it is the same problem.
November 28, 2011 at 11:21 pm
If the problems still remains. Send me the screenshot at allnewankur[at]gmail[dot]com

fullscreen is working…bt program is not responding to any of my commands…while in normal window its working perfectly fine…plz help..thank you..
November 28, 2011 at 11:18 pm
Well, try it again. DosBox emulator is not 100% compatible as far as I know. Your case could be the one in gray. If it still doesn’t work, give it a last shot by uninstalling and following the process again.
All the best.
November 27, 2011 at 2:03 pm

dosbox work in fullscreen mode but afterv one program is run sucessfully
for another mouse didn’t move i tried dosbox option to correct mouse lock but nothing happens.
December 23, 2011 at 12:07 pm
Why you need mouse to work, anyway? Use keyboard shortcuts, Prabhakar. Mouse is tiresome, no?
December 6, 2011 at 1:39 pm
in my tc\bgi the graphics related some application is not there so from where i can download it.
December 23, 2011 at 12:05 pm
It originally works. All libraries are at place. Check what syntax you are using. You need to use double \\ to mention the address in graphics program, afaik.
December 21, 2011 at 6:04 pm
i finished download… wen i click [TC3setup.exe] …. its shows…
The version of this flies is not compatible with the version of windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.
wat i must do… can anyone pls help me pls soon……………

January 13, 2012 at 8:24 pm
c:\TC>cd bin
unable to change to: bin.
how can i solve this problem
January 13, 2012 at 9:15 pm
You followed some step incorrectly. Type ‘dir’ to list what you have in present directory. Go through steps again for more help.
Good luck.
January 13, 2012 at 9:27 pm
thank you sir….
but now it say invalid directory. when i click ok, c++ program runs.
any problem here?
January 15, 2012 at 1:53 pm
As long as your program is running comfortably, you shouldn’t worry about that part.
If you still want to rectify it, check that your TC actually has BIN or not. Pick up the link of setup from post and try using that with same instructions. Will work.:)
Good luck.
