reverse order

[Mikkiii123]

hello all, i'm suppose to give the output in reverse order. in the code below, is the regular order. I'm having trouble of how to reverse it

  #include <iostream>// cerr = error output stream
#include <cstdlib> //exit
#include <string>//strings
#include <fstream>// file streams
using namespace std;
int main ()
{
    double eastSt, eastEl, westSt, westEl;
    string date, earlier_date, later_date ;
    //get dates from user
    cout << "Enter earlier date: " << endl;
    cin >> earlier_date;
    cout << "Enter later date: " << endl;
    cin >> later_date;
    // Setup data structure
    double myData [400] ;
    //input file stream
    ifstream fin("Current_Reservoir_Levels.tsv");
    if (fin.fail())
    {
        cerr << "File cannot be opened for reading." << endl;
        exit(1);
    }
    string junk;
    getline(fin, junk);
    // loop reads the file line-by-line
    while(fin >> date >> eastSt >> eastEl >> westSt >> westEl)
    {
            // specific dates
            if ( (date >= earlier_date) && (date <= later_date ))
            {
                for (int i = 0; i < 1; i++)
                {
                    myData [i] = westEl;
                    cout << date << " " << myData [i] << " ft" <<  endl;
                }
            }
    }
    fin.close();
    return 0;
}
