In vc6, I in the graph. H, defines the structure of the ray in. CPP wrote in the following two methods, compile time, however, suggests that thunder is not defined, how is this to return a responsibility excuse me? My other structures are not an error,

. Also, I use a graphics library function circle of h (int, int, int) circle, but compile-time hint parameter error, thank you for the great god

Graphics. H is third-party libraries?
