    // compile with: /EHsc
    // Illustrates the vector::empty and vector::erase functions.
    // Also demonstrates the vector::push_back function.
    //
    // Functions:
    //
    //    vector::empty - Returns true if vector has no elements.
    //
    //    vector::erase - Deletes elements from a vector (single & range).
    //
    //    vector::begin - Returns an iterator to start traversal of the
    //                    vector.
    //
    //    vector::end - Returns an iterator for the last element of the
    //                  vector.
    //
    //    vector::push_back - Appends (inserts) an element to the end of a
    //                        vector, allocating memory for it if necessary.
    //
    //    vector::iterator - Traverses the vector.
