Reading formated date from a file C++

Question

So I have this file with multiple dates like this:

2.10.2015
13.12.2016
...

I'm wondering how to read from this file and store day, month and year into 3 separate integers.

Thanks.

Answer 1

Given an istream foo which contains the dates you'll want to use get_time:

vector<tm> bar;
tm i;

while(foo >> get_time(&i, "%d.%m.%Y")) bar.push_back(i);

Of course defensive input is best practice, and doing that can be very challenging for a complex input type like a date. If you're going for that you might find this helpful: https://stackoverflow.com/a/29413535/2642059
