//required nested for loop to sort State objects vector named states.

//assuming name field in State is public.

//using bubble sort algorithm

//looping from i=0 to states.size()-1

for(int i=0;i<states.size();i++){

                //looping from j=0 to states.size()-i-2

                for(int j=0;j<states.size()-i-1;j++){

                                //comparing names of states at j and j+1

                                if(states[j].name > states[j+1].name){

                                                //swapping states at j and j+1

                                                State temp=states[j];

                                                states[j]=states[j+1];

                                                states[j+1]=temp;

                                }

                }
