problem with memory allocation in C++

Tiago Jorge Sequeira Martins · 2011-06-21T13:04:33

Hi everyone, it's my first post, and don't really know if this is the right section, but here it goes: I'm new in C++, made some simples programs and now I'm trying to make something with C++ and openGL, today i tried to create a TriangleMesh class, which creates a mesh of triangles giving the number of triangles of each side, the inicial point and the size of each catete, until now everything went great, but today i got a bug and can't resolve it I allocate a new array of Vector3f and Triangles (all done by me) and then I start some loops to create the Vectors and after that the triangles inside the array, the problem is,at some point, the Vectors get deleted without me calling a destructor Is it legal to post here my code so you guys can try to find the problem?

^ If you're returning multiple values, you should probably use references. Pointers is more like C style than C++

I understand this and that is why I emphasized with the word SOMETIMES in all caps.

I solved the problem, had an error in the algorithm when calculating the index of each vertex for the triangle, it was acessing a forbidden memory adress, solved that using the vector<>

thanks to everyone for the tips =)
