glColor3f(0.0f,0.1f,1.0f);
glRasterPos2i(200, 400);
FontPrintf(Font, -1, “Testing Opengl”);

glFlush();

and i get compilation error:
‘FontPrintf’ : undeclared identifier
‘Font’ : undeclared identifier

You need to link with the library or source file(s) that defines that function and whatever Font may be, and they are not related to OpenGL. The place where you got that piece of code would be a good place to start.
