Initgraph, I don't understand this function, is set the display mode? You draw round with a graphical display, the income, according to the character to use character to toggle display mode,CodePudding user response:
Graphics. H is the inside of the TC graphics library, if want to use the TC should be used to compile, divided into: pixel function, linear and linear function, polygonal functions, filling function, etc., but when we're using vc6.0 compiler and visual studio 2013 is in the compiler doesn't support graphics. H graphics library, of course, vc6.0 and visual studio 2013 compiler also comes with Microsoft graphics library API (also called Windows API, its function basically included in Windows. H header file), so if we want to use graphics in vc6.0 and visual studio 2013 graphics library? We have two solution,CodePudding user response:
