stoi is giving me "abort has been called()" error.

So i have been learning how to overload>> after making my own structs. So i am currently trying to add info from a text file into my struct. However one of the structs is in int format but the numbers i get from the textfile is in string so i am trying to convert them to int using stoi function.

TEMPziptot looks like it is all numbers but it also looks like there might be a last line that is empty. Maybe this is making it crash? It crash in the beginning of the program and i cant run my program at all.

if i remove the code on line 26 it works just fine but then i cant add the numbers to my struct since it need to int format and not string format.

Thanks for the help!

istream& operator>>(istream& in, person& p)
{
	string TEMPinfo;

	getline(in, TEMPinfo);
	transform(TEMPinfo.begin(), TEMPinfo.end(), TEMPinfo.begin(), ::tolower);
	p.name = TEMPinfo;

	getline(in, TEMPinfo);
	p.id = TEMPinfo;

	address TEMPaddress;

	getline(in, TEMPinfo, ',');
	TEMPaddress.street = TEMPinfo;

	string TEMPzip1;
	string TEMPzip2;
	in >> TEMPzip1;
	in >> TEMPzip2;

	string TEMPziptot = TEMPzip1 + TEMPzip2; //Adderar string(zip1) och string(zip2).

	cout << TEMPziptot << endl;

	TEMPaddress.zip = stoi(TEMPziptot); //Konverterar från string till int.

	getline(in, TEMPinfo);
	TEMPaddress.city = TEMPinfo;

	return in;
}

If TEMPziptot is empty, don't call stoi but set the zip to some known bad marker value.

For example,

if (TEMPziptot.size() > 0)
{
  TEMPaddress.zip = stoi(TEMPziptot);
}
else
{
  TEMPaddress.zip = -1;
}

There could be other things that go wrong, that you should think about. Could the string ever contain letters, for example?

Thanks, that worked perfect for me. However i decided to no use else her since i dont need to return a bad marker value, it is just better for the empty line to "disappear".
