Borland Turbo C ++ in full screen mode

Borland Turbo C/C++ compiler has a problem working in full screen. Read this article to fix the full screen mode in Turbo C++.

C++ is an object oriented programming language which is used to program most of the software available today. There are many compilers available for writing C++ programs. One of the compilers is TurboC3. It does the job of compiling as well as running your program. When there is an error it shows the error along with the reason and the line number where the error has occurred. So, it is a very easy compiler available out there for programming in C++. But a problem with TurboC3 is that it does not work full screen in Windows 7. It shows and error message when you try to make it full screen that 'This system does not support full screen mode.' It works well in Windows XP. Because of this problem in Windows 7, it is not comfortable to use TurboC3 in Windows 7 in a small screen.

If you encounter such a problem there are certain things that you can do to fix it.

1. Dosbox:

You can download software called Dosbox which is an emulator for running DOS games on Windows. This software is free to download. You can download it from After downloading and installing the software you need to open it and type the following command in it:
(Note: Before doing this you need to make sure the your TC folder i.e. the turboc3 is located at the C:\ drive.)
  • Mount the drive by typing 'mount c: c:/tc' and hit the Enter key.

  • Type 'c:' to enter the C prompt.

  • Now open the bin folder by typing 'cd bin'.

  • Now start the tc.exe by typing 'tc' and hitting the Enter key.

  • This will open the TC.exe i.e. the C++ compiler in Dosbox. Now if you are not in full screen mode, just press Alt+Enter keys to go to full screen mode. Now you can program as usual with the TurboC3 compiler.
    You will notice one more thing that when you include header files like iostream.h, you will encounter another error that the compiler cannot find the file. To fix this problem you have to go to the Options menu and click on the Directories option. Then you have to change the include and libraries directories to C:\include and C:\libraries respectively.

    2. Safe Mode:

    The other thing that you can do to fix this problem is to boot your computer in the safe mode. When the computer boots press the F8 key and this will give you the option of logging into the safe mode. Safe mode is a mode where only a minimum set of programs are available. You can run turboc3 in safe mode without any problem.

    3. Windows XP mode:

    This is a method to run other Windows XP operating system in your current operating system. You can download Windows XP mode from the internet and install it. This mode is used to run older versions of certain software that are only compatible with XP on Windows 7. So, you can use this option to run Turboc3 in Windows XP inside Windows 7 without any hassle.
