Deleting elements in a vector of pointers to vectors of objects

Question

I have a vector set up as follows:

vector< vector<myClass>* > vec;

I am having trouble deleting elements from vec however, I have dynamically allocated all elements in vec, and am trying to delete the ith element as follows:

vector<myClass> *victim = vec[i];
delete victim;
victim = 0;

However this does not seem to be correctly removing them from vec. What am I missing here?

try using vector::erase to remove it from the vector. The delete will free the memory only but the vector will keep the pointer unless you removed it.
