!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How do I check condition if a variable(f1var) for file 1(fileone.txt) is equal to the first variable(f2var) in file 2(filetwo.txt). And if they are equal, I am trying to output the 1st variable(f2var) and 2nd variable(f2var2) of file 2(filetwo.txt) as an output.

#include <iostream>
#include <string>
#include <fstream>
#include<stdlib.h>
#include<string.h>
#include<ctime>
using namespace std;


int main()
{
    
    string f1var;
    string f2var, f2var2;
    int counter;
    ifstream y("fileone.txt");
    ifstream x("filetwo.txt");
        while((getline(y,f1var) && getline(x,f2var);getlin(x,f2var2)
        {
                if(f1var==f2var)
                {
                        counter=1;
                }
        }
        y.close();
        x.close();
        if(counter==1){
            cout<<f2var<<f2var2<<endl;
        }

    return 0;
}
