They should be *(float* x, float* y, int pts) It doesn't matter what you call it with if you declare it improperly.

I think tribe did that. That's what I get for not previewing.

If there is any other problem it is in the caller of polygonPerimiter or within segmentLength. Try to follow all the other changes and figure out why I did them. Each one is important. float segmentLength(float, float, float, float); float polygonPerimeter (float *x, float *y, int pnts) { float d=0.0; int i; for (i=0; i<pnts; i++) d += segmentLength (x[i], x[i+1], y[i], y[i+1]); return d; } Wed, 17 Mar 2004 15:13:26 GMT http://CPP.tribe.net/thread/78170b9a-a4e7-4420-905b-05ca95363f55#1b5c08e1-9a33-4576-9402-ba5b32dea9b6 Bill 2004-03-17T15:13:26Z http://CPP.tribe.net/thread/78170b9a-a4e7-4420-905b-05ca95363f55#263d1c81-1ffb-4dec-90d2-ba5a4d4e97cf hint: I left one major problem for you.
