Question

Let’s say I have a string that has multiple carriage returns in it, i.e:

394968686
100630382
395950966
335666021

I’m still pretty amateur hour with C++, would anyone be willing to show me how you go about: parsing through each “line” in the string ? So I can do something with it later (add the desired line to a list). I’m guessing using Find(“\n”) in a loop?

Thanks guys.

You could try it using stringstream. Notice that you can overload the getline method to use any delimeter you want.

string line;
stringstream ss;
ss << yourstring;
while ( getline(ss, line, '\n') )
{
  cout << line << endl;
}

Alternatively you could use the boost library’s tokenizer class.
