Multiple Class Need Same Parameter (how to optimize),

Hi this question might some a little bit stupid(the question title might not be not relevant going to change until found a perfect title), i had spend couple hours figuring this out.

i'll try to explain as details as i could. First i will give the code of mine first.

File 'main.cpp'

using namespace std;

void readFile(Vector<WindLog> &VecObj);
void showMenu(Vector<WindLog> &VecObj);
void option1(Vector<WindLog> &VecObj);
void option2(Vector<WindLog> &VecObj);
void option3(Vector<WindLog> &VecObj);
void option4(Vector<WindLog> &VecObj);
void option5();
int getUserChoice();
int getMonthInput();
int getYearInput();

int main()
{

    Vector<WindLog> Obj;
    readFile(Obj);
    showMenu(Obj);

    return 0;
}

void readFile(Vector<WindLog> &VecObj){

    Date date;
    Time time;
    float s, sr;
    WindLog wLog;
    string token, filename, line;

    ifstream myFile("testfile.csv");
    getline(myFile, line); //to skip header information ;

    if(myFile.is_open()){
        while(getline(myFile, line))
        {
            stringstream ss(line); // <-- pas line to stream

            getline(ss, token,'/'); // <--Token for day;
            date.setDay(atoi(token.c_str()));

            getline(ss, token,'/'); // <--Token for month;
            date.setMonth(atoi(token.c_str()));

            getline(ss, token,' '); // <--Token for year;
            date.setYear(atoi(token.c_str()));

            getline(ss, token,':'); // <-- Token for Hour;
            time.setHour(atoi(token.c_str()));

            getline(ss, token,','); // <-- Token for Minute;
            time.setMinute(atoi(token.c_str()));

            for(int i = 0; i<9; i++)
                getline(ss, token, ',');

            getline(ss, token,','); // <-- Token for WindSpeed
            s = atof(token.c_str());

            getline(ss,token,','); // <-- Token for Solar Radiation
            sr = atof(token.c_str());

            wLog = WindLog(date, time, s, sr);
            VecObj.add(wLog);
        }
    }
    else{cout<<"No File Opened"<<endl;}



}
void showMenu(Vector<WindLog> &VecObj){
    int choice;

    while(true){
        cout << "\t\tOptions Menu" << endl;
        cout << "<------------------------------------------->" <<endl;
        cout << "1) Show Maximum Wind Speed for Specified Month and Year." << endl;

        cout << "3) Show Total Radiation in kWh/m^2 for each Month of Specified Year." << endl;
        cout << "4) Print Average Wind Speed and Total Solar Radiation for each month of Specified Year, to File('WindandSolar.csv')." << endl;
        cout << "5) Exit Program." << endl;

        choice = getUserChoice();

        switch(choice)
        {
            case 1:option1(VecObj); break;

    }
    return tempYear;
}


void option1(Vector<WindLog> &VecObj){}
void option2(Vector<WindLog> &VecObj){}
void option3(Vector<WindLog> &VecObj){}
void option4(Vector<WindLog> &VecObj){}
void option5(){exit(0);}

Let me explain ( if something not clear please give some comment i'll add more specific detail, just into c++ for about 1 month ).

at main i declare Vector<windLog> Obj to store my windlog file. then i need to pass it to void readFile(Vector<WindLog> &VecObj); for some read file and add into the Vector Class i created.

after that the program will goes void showMenu(Vector<WindLog> &VecObj); and showing the menu options and User entered choice, from 1 to 5;

one of this function will executed based on user choice.

void option1(Vector<WindLog> &VecObj); void option2(Vector<WindLog> &VecObj); void option3(Vector<WindLog> &VecObj); void option4(Vector<WindLog> &VecObj);

my question is the parameter of option1 - option4, they has the same parameter and that bother me, i dont know whether if its okay or not.

If any of my question are not clear, please give me some comment so i could fix it. and if you guys want to give me some advice on my code, i would really appreciate it.
