C++: memory leak on clear()?

[neurojim]

Hi, I was wondering whether for a 3d vector array whether there would be a memory leak if the array is deleted by a single clear() command:

typedef vector<int> vint;
typedef vector<vint> vvint;
typedef vector<vvint> vvvint;
 
vint oned;
vvint twod;
vvvint threed;
int i;
 
for (i=0; i<10; i++)
  oned.push_back(1);
 
for (i=0; i<10; i++)
  twod.push(oned);
 
for (i=0; i<10; i++)
  threed.push(twod);
 
// ...
 
threed.clear();

No I think it will be fine the created classes will all be destructed correctly, each destructor emptying and destructing it's own contents if it is a vector.
