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

You could try something like this:

// construct stream object and open file 
std::ifstream ifs(file_name.c_str());

// check if opened successfully
if (!ifs) std::cerr <<"Can't open input file!\n";

int year, month, day;
char dot;

// extract date
ifs >> day >> dot >> month >> dot >> year;

// check input format
if (dot != '.') // add ranges for month and days validity
{
    std::cerr <<"Wrong date format!\n";
}

The above code could be placed in a (while) loop reading the file line by line.
