Starting an iterator from a random position in a vector. Is this doable or sensible

Rather than starting from myContainer->begin() or myContainer->end(), I want to set my iterator to a arbitrary position in my vector, something like myContainer (which I tried, but that gives me the ith element in the container) Being a vector iterator & since vector's are a random access container, I took a look at the random_access iterator reference and found a [] operator. But that too returns the ith element, which does make sense when you think about it.

You can do it like this:

typedef std::vector<SomeType> TSomeTypeList;
TSomeTypeList myContainer;

TSomeTypeList::iterator randomIter = myContainer.begin() + rand() % myContainer.size();
