C++ generator of curves

Sorry, have misplaced the original generator. I load the code that does almost the same picture.

Files SuperFactorial.cin ado.cin conto.cin should be loaded to the working directory in order to compile the C++ code below:

 #define DB double
 #define DO(x,y) for(x=0;x<y;x++)
 using namespace std;

 typedef complex<double> z_type;
 #define Re(x) x.real()
 #define Im(x) x.imag()
 #define I z_type(0.,1.)
