用“>>”从文件中读取

Question

I have the following persons file:

Name 0744112233 ASD

and the following piece of code

const string InFilePersonRepository::PFILE = "persons";

void InFilePersonRepository::load() {
        string delim = " ";
        string name, phone, address;
        ifstream fin(PFILE.c_str());
        while (fin.good()){
            fin>>name>>delim>>phone>>delim>>address;
            Person p(name,phone,address);
            persons.push_back(p);
        }
}

After the reading is done, the values of name, phone, address are: name = Name, phone = ASD, address = "",

If the files has multiple lines, same problem, the second field in file is skipped. Why is that happening?

Thanks

Answer 1

>> skips whitespace, so there is no need for delim . fin >> name >> phone >> address should do.

Answer 2

Try something like that

 void InFilePersonRepository::load() {
            string name, phone, address;
            ifstream fin(PFILE.c_str());
            while (fin.good()){
                fin>>name>>phone>>address;
                Person p(name,phone,address);
                persons.push_back(p);
            }
    }
