These days I've studied operator overloading and after that I tried to overload >> operator with ifstream for files.
I'm wondering why this program doesn't show me the data I'm trying to get from the file dati.it USING THE OP. OVERLOADING. Without the function ifstream& operator>>(ifstream& c, string& s) it works fine, but I want to do the job with the overloading
I know it's a simple stupid example but it's for learning... what's wrong with it? (I'm getting no errors, just not doing what I want)#include <iostream>
#include <fstream>
using namespace std;
ifstream& operator>>(ifstream& c, string& s) {
c >> s;
return c;
}
int main()
{
const int dim_max = 1000;
char name[dim_max];
char surname[dim_max];
char email[dim_max];
string lista;
// 1.input
cin.getline(name, dim_max, '\n');
cin.getline(surname, dim_max, '\n');
cin.getline(email, dim_max, '\n');
// writing to file
ofstream Fileobj;
Fileobj.open("dati.txt");
Fileobj << name << endl << "#" << endl << surname << endl << "#" << endl << email << endl << "#" << endl;
Fileobj.close();
// 2.output
ifstream Fileobjx("dati.txt");
while (!Fileobjx.eof()) {
Fileobjx >> lista;
cout << lista;
}
cout << "Ok" << endl;
return 0;
}
