How to have full screen control from a c program?

[benny7440]

I remember that from a very basic BASIC running machine I had that capabilities at hand, by default, since the early '80's.

How can I achieve the same results from c?

For ex., I've seen that there're some codes that render the dominoes pieces or cards as used in poker. I need to use some symbols like those & they need to be placed in the screen at arbitrary locations & orientations. Need to change the background color without loosing any symbol present there already.

It should be possible but I don't know where to look for it. Thanks for any tip/help on this!
