If you are using windows 7 and running turbo c / c++ you will definately get this error "This system does not support fullscreen mode. Choose 'Close' to terminate the application."
So This error occurs due to c/c++ programing is very old and still used it requies 16bit mode which can't be done in windows 7
so i have a solution how to make this screen into fullscreen
Because full screen is necessary to type larger programs and decreasing the chances of error in c++/C programming
