pointer trouble
ahh, things are starting to clear up...thanks a lot for you detailed explanations! -
pointer trouble
here's my reasoning: allPoints[0] returns double[3] so &(allPoitns[0]) returns a pointer to double[3]? I also tried without the "&" since i'm thinking double[3] is actually an address of the first element of the array... but it's giving me an error saying that there is a difference... -
pointer trouble
p_3d is actually an API typedef, and it's used to hold XYZ coordinates of points in 3-space. mmm, my application (not stress test!) is that I have a solid, and have a triangulated mesh genereated, which means i've created a surface out of adjacent triangles that entirely covers my solid. my... -

deleting memory
If I have a function struct myStruct{ double myDouble; } func(vector <myStruct> &myVector){ myStruct dynamicMyStruct; dynamicMyStruct = new myStruct; myVector.push_back(dynamicMyStruct); } how do I delete the memory associatted with dynamicMyStruct? I cannot delete it at the end of the... -
pointer trouble
instead of using a vector, what should I use? crap, i copied that code entirely wrong...i actually have triangle tri tri.points[0] = &(allPoints[0]); a little bit confused on what allPoints[0] returns...a struct? or an address? thanks a lot! -
pointer trouble
if: typedef double p_3d[3]; and struct triangle{ p_3d* points[3] // three points to p_3d } and I have a vector <p_3d> allPoints, when I do triangle.points[0] = &(allPoints[i]) I get '&' requires l-value what is the correct way to do this assignment? thanks! -
removing duplicates, updating pointers
I have an array of points, which form the vertices a triangles. I also have an array of triangles, each of which has a 3 pointers pointing to 3 elements of the array. The original array contains duplicate points, as one point may be the vertex of more than one triangle. I need to delete all... -
security
sort of...except that I'm hoping that when I move my code to another computer, and i recompile on that computer, a C++ function will read the computer's ID, instead of me having to find out manualy the ID and code it as some kind of string literal..but then, there's also the problem of how to...
