i need simple problem.. i'm trying learn c++ want game programming, have previous programming experience, not in c++.. question comes little this. i'm making dummy console application take numbers of current xyz , compare box of coords.. [x1,z1,y1 / x2,y2,z2] , check if you're within area.. can on own.. question is, how write allow reuse function have different output, eg if within x box x, if in y box y .. have..
void withinrange(int x1, int y1, int z1, int x2, int y2, int z2) { if (ccoordx > x1 && ccoordy > y1 && ccoordz > z1 && ccoordx < x2 && ccoordy < y2 && ccoordz < z2) { } } i'm not sure how expand on make able reusable function..
you asked:
how write allow reuse function have different output, eg if within x box x, if in y box y
- write different functions check whether value in x box or y box.
- implement
withinrangeusing other functions. - use returned values of these functions make decisions in calling function(s).
bool withinxrange(int x1, int x2) { return (ccoordx > x1 && ccoordx < x2); } bool withinyrange(int y1, int y2) { return (ccoordy > y1 && ccoordy < y2); } bool withinzrange(int z1, int z2) { return (ccoordz > z1 && ccoordz < z2); } bool withinrange(int x1, int y1, int z1, int x2, int y2, int z2) { return ( withinxrange(x1, x2) && withinyrange(y1, y2) && withinzrange(z1, z2) ); } in calling function:
int x1 = <some value>; int x2 = <some value>; if ( withinxrange(x1, x2) ) { // }
