I'm attaching the source code of a C++ program that is compiled with Turbo C++ compiler on virtual box. The program is intended to make an animation of a man walking in
rain with an umbrella. Anyone with some C++ skills can patch the code. Clearly comment any changes. Anything that seems to be good should done to the source code. And
make your suggestions at the end. And please try to manage a SDL Linux alternative of
the program on the move. Manage the source code as follows.

  • When you change a line comment the previous one and code in the alternative.
  • When you add something, document it clearly
  • Manage the same source code.
  • After making changes compile it and push back.
  • Do not stick with the latest source code but with the best.
  • Don't spam please.
  • Try to make portable code...

//Here is the code...

int sineGen(int cntr)

Yeesh ... bad practices.

The best thing to do is, check in to bitbucket, github/gitorius ... or even a gist.

 Do not comment the previous line and code the alternative ... simply remove it.

Use Qt and QPainter on a custom widget... will make your life much easier.

This was a good example of OOP(Object oriented programming).Although not completely following OO paradigm.
you should have attached the source rather than typing every thing here.

Yes I know. But this is for someone who starts programming...
And understand how git, launchpad or any other cvs works basically...
Turbo C++ is not a free-ware too you know...
Just coding....

You can get graphics.h work in GNU/Linux with few simple steps. Follow the link,

http://sector-zero.blogspot.com/2007/07/graphicsh-in-gnulinux.html

Posted by Rajiv R Nair.

If you want to do mouse programming using int86() using dos.h then probably you will have to do that with Turbo C and DosBox. If you are working for the labs then I think you need to learn the mouse programming also, so you have to use Turbo C.

These things are not applicable for a common man, as BGI Graphics is now used only in Colleges to teach the basics of computer graphics.

Indeed. For GUI programs, one should use a modern toolkit like Qt. I've
heard that 'Allegro' (http://alleg.sourceforge.net/) is a good library
for graphics/game programming. It's cross-platform too.

@Subin
It's good to see some nice cleanly indented code! Kudos to you.
You should really get rid of this archaic TurboC compiler and try some
newer standards compliant compilers.

Thank for the reply to all.
I'm still in my college...!
And if anybody suggest a SDL diff of the program...Just code it....
regards to all.....
