C++ question

Show any changes needed to overload the following good_bubble function to sort a vector of Date objects: void good_bubble(vector char & data, vector :: size_type start, vector : size_type end) vector :: size_type loop = 0, cur: bool done = false: while (loop data[cur+1]) { swap(data[cur], data[cur+1]): done = false: } loop++: } return: You happen to know that the Date class provides the method: bool Date: greater (const Date & other) const: (... if this helps.) You need only show the lines that must change! Suddenly you realize that you'll need one more piece of code for this new sort routine to work
