Question

I need help with this program c++ - console aplication

The attached file is a list of all the Long Island Railroad stations. Each station is described on one line with six space-delimited fields. Each station has a unique 3-character numeric ID, a station name, a branch to which it belongs, a list of the IDs of other stations to which it connects, the station's longitude and latitude, and a final field describing the source of the information.

Write a program to read in the station data and store it by branch. After reading and saving the data, display the station names and ID's by branch as shown below.

The following structure can be used to store the station data:

        struct Station
        {
            std::string station;
            std::string id;
        };

A class can be used instead. Use a map to store an entry for each branch. One approach to the data structure design would save the Stations of a branch, the values of the map, as vectors of Stations. The following types might be helpful.

typedef std::vector<std::string> Strings;
typedef std::vector<Station> Stations;
typedef std::map<std::string,Stations> StationBranchList;
typedef std::map<std::string,Station> StationMap;

If we have a declaration such as map<...> lirr; so that lirr is a map of branch names, which are strings, to vectors of Stations, assuming the structure Station defined above, then to add a station (the variable sta) to the vector of stations associated with a branch, use the statement

lirr[branch].push_back(sta);

.push_back() makes a copy of its argument and adds it to the end of the vector.

Extra Credit

Add to the program another level of output that for each station displays all the stations to which it connects. Sample output is shown following the assignment output.

Sample Output

For example, read this output as: in the City Terminal Zone branch, the station whose ID is 014 named East New York connects to station 013 Nostrand Avenue and station 015 Jamaica.
