How to convert this vector code into a class? - c++

Question

I was trying to put this code into a class but I couldn't manage to do it. The job of the function is pulling team names from a .txt file and putting them in a vector. I think the main problem is I couldn't select the right function return type.
This is the teams.txt: (The names before the "-" symbol are teams. Other names are unrelated with my question but they are coachs of the teams.)
Trabzonspor-Abdullah Avcı+
Fenerbahçe-Vítor Pereira+
Beşiktaş-Sergen Yalçın+
Galatasaray-Fatih Terim+
İstanbul Başakşehir-Emre Belözeoğlu+
Alanyaspor-Bülent Korkmaz+
Fatih Karagümrük-Francesco Farioli+
Gaziantep-Erol Bulut+
Adana Demirspor-Vincenzo Montella+
Ankara Dinc-Nestor El Maestro+
Antalyaspor-Nuri Şahin+
Kayserispor-Hikmet Karaman+
Yeni Malatyaspor-Marius Sumudica+
Konyaspor-İlhan Palut+
Sivasspor-Rıza Çalımbay+
Hatayspor-Ömer Erdoğan+
Giresunspor-Hakan Keleş+
Kasımpaşa-Hakan Kutlu+
And this is the my code who does the putting them in a vector:
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std; //I know that's a bad practice but i just need to do this for while
std::string process(std::string const& s) //A function to seperate teams from the coaches
{
string::size_type pos = s.find('-');
if (pos != string::npos)
{
return s.substr(0, pos);
}
else
{
return s;
}
}
int main() {
ifstream readTeam("teams.txt");
if (!readTeam) { //checking that successfully opened the file.
std::cerr << "Error while opening the file.\n";
return 1;
}
vector<std::string> teams;
string team;
while (getline(readTeam, team)) {
teams.push_back(process(team));
}
readTeam.close();
int g = 1;//for printing the teams, just for displaying it. doesn't have to in a class.
for (const auto& i : teams) {
cout << g;
cout << i << endl;
g++;
}
return 0;
}
And that's what i did(tried) to make it a class:
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
std::string process(std::string const& s)
{
string::size_type pos = s.find('-');
if (pos != string::npos)
{
return s.substr(0, pos);
}
else
{
return s;
}
}
class readFile {
public:
void setTxtName(string);
vector<unsigned char> const& getTeam() const{
}
vector<string> teams;
private:
string fileName;
};
int main() {
readFile pullTeams;
pullTeams.setTxtName("teams.txt");
return 0;
}
void readFile::setTxtName(string txtName) {
fileName = txtName;
}
vector<string> const& readFile::getTeam { //problem is defining it(I think). So I couldn't add my main code int it..
return teams;
}
Anything helps, thank you!

I did a little different research based on the Botje's comment. And I manage to create an answer based on here. Thanks.

int g = 1;//for printing the teams, just for displaying it. doesn't have to in a class.
for (const auto& i : teams) {

bool readFile::read(string txtName) {
ifstream txt;
string team;
txt.open(txtName.c_str());
if (!txt.is_open())
return false;
while (getline(txt, team))
teams.push_back(process(team));
return true;
}
vector<string> readFile::getTxt() {
return teams;
}
