c++ - GDI CreatePolyPolygon and boost multi_polygon -


there winapi function following prototype:

winapi createpolypolygonrgn( point *pptl, int  *pc, int cpoly, int imode);

i can't realize best way convert multipolygon representation accepted procedure multi_polygon boost model. in case of interior-free polygon set conversion multi_polygon evident.

but if have interiors don't see easy way of conversion because need detect interiors first , correspondence polygons. it's easy collect exterior , interior polygons exterior polygons , put multi_polygon. how put interior polygons represented exterior corresponding polygon interior rings?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
