Hello I have a problem with separating input data from the file. I want it to be separated with some kind of delimiter instead of space. Data in file are represented like this:

street;num
street;num
...

Adress structure:

struct adress
{
    std::string street;

    int num;
};

std::istream &operator>> (std::istream &in, adress &adr)
{
    in>>adr.street >>adr.num;

    return in;
}

You could read it into a `string` with the existing `operator>>`. Then, find the `;` and separate the substring before and after. – Scheff's Cat Nov 11 '21 at 14:03

The slightly misnamed `std::getline` takes a "line separator" argument, which can be any character you want. – molbdnilo Nov 11 '21 at 14:19
