How to create a filereading program that loads a file of codes

Basically my program is giving me a load of errors with my filereading program when trying to compile. The goal is to get the user to enter the threshold number and the strings that are equal to or greater than that threshold number will be outputted. The program fails at that because there are several errors with the code. How to fix the errors within the code?

   #include <iostream>     #include <fstream>     #include <cstdlib>     using namespace std;         int read_airports(string cities[], int threshold);         int main()    {        ifstream fin;           fin.open("airports.txt");           if (fin.is_open())        {            string cities[20];            int count, threshold;               count = read_airports(cities, threshold);            while(!fin.eof())            {            fin >> threshold;            cout << "Enter a threshold number" << endl;            cin >> threshold;               if (fin.good())            {                if (cities >= threshold)                {                    cout << cities << endl;                }            }              }            fin.close();        }           return 0;    }          int read_airports(string cities[], int threshold)    {    }
