title: C++ convert string date (1/4/2000) to int date (20000104)
body: <p>I can write a function to parse the string date, but I feel like I am re-inventing the wheel here. Is there a faster, perhaps built in C++ way to get from a string date of this format: 1/4/2000 to a more easy to use int like 20000104?</p>
