I would like to link C++ with a graphical interface (an x-y coordinate system). Is there a program that works well with C++ for this? If so, what process would I follow to do this?
you can use the borland c++ for the basical graphic design. There you can use the coordinates you want. The borland c++ have few functions for grapfic design. The only issue is that you need to initialize the graphic using a command and to add the graphics.h library.
