There is no such function as sector in C++. You probably mean the sector function that was originally provided by Borland's Graphic Interface library (BGI), now owned by Embarcadero, but you won't find this function in any standard implementation of C++ since all graphics coding is platform-dependent. That is, C++ is intended to be generic and therefore has no built-in graphics support whatsoever; you have to use a graphics API and library that supports your specific platform's graphics devices. That said, the Borland/Embarcadero version of the sector function is typically used to draw and fill a pie-chart segment of an elipse (or circle). As such it probably isn't the best function for drawing stylised clouds. You'd probably be better off using a series of arc functions instead.
