I have 3 files for a small project that I'm working on. The files are main.cpp, Airline.h (This is where my classes are stored) and Airline.cpp (This is where my functions are stored).
As of now, when I test the code out, I get an error that says:
undefined reference to "programInformation::mainMenu()
Can anyone see if there's any issues in my files, and how I have my folders set up?
#include <iostream>
#include "AirlineClass.h"
using namespace std;
void programInformation::mainMenu(){
cout << " Welcome to DFW Airport " << endl;
cout << "=================================" << endl;
cout << "------------Main Menu------------" << endl;
cout << "1. Customer Details" << endl;
cout << "2. Flight Registration " << endl;
cout << "3. Ticket and Charges " << endl;
cout << "4. Exit" << endl;
cout << "Select Option" << endl;
int option;
cin >> option;
switch(option){
case 1:
{
customerInformation info;
info.obtainInformation();
info.displayInformation();
break;
}
case 2:
{
}
case 3:
{
}
case 4:
{
}
}
}
