C++ program that sees if the content of n files in a .txt is the same.

#include <iostream>
#include <fstream>
using namespace std;



int main() {
    int n,i;
    cout << "Dati n fisiere: " << endl;
    cin >> n;
    ifstream f;
    ofstream g("fisier_copie.txt");

    char FileName[20], linie[250], linie2[250];

    cout << "Nume: ";
    cin >> FileName;
    f.open(FileName);
    while (!f.eof()) {
        f.getline(linie, 250);
        g << linie << endl;
    }
    f.close();

    for(i=1;i<n;i++){
        ifstream g2("fisier_copie.txt");
        cin >> FileName;
        f.open(FileName);
        while (!f.eof()) {
            f.getline(linie, 250);
            g2.getline(linie2, 250);
            if (strcmp(linie, linie2)==0) {
                cout << "sunt egale";
                cout << endl;
            } else {
                cout << "nu sunt egale";
                cout << endl;
            }
