Facing little problem in c-programming

hello all :slight_smile:
i have started learning c language few days ago. yesterday i downloaded turbo c++ 3.2.2
i created a program in this and after compiling while i am trying to start the program it is showing a message
as the following picture. someone please help me to get rid of it.

Let’s just not use a discontinued compiler. I suggest installing cygwin and using gcc or g++
