Lesson 19 - Date and Time in C++

In the previous lesson, Introducing Vector in C++, we discussed the vector container. In today's C++ tutorial, we're going to look at the representation of date and time in C++ programs and get ready for the next lesson when we're going to program a simple diary.

Time is one of the most difficult topics in programming. Since the calendar is not predictable, it's not easy to work with time at all. For example, we all know that every year divisible by 4 is a leap year, but that's not entirely true. This rule does not apply to years divisible by 100 (for example, the year 1900 was not a leap year), but it also applies to years divisible by 400 (that's why the year 2000 was a leap year). We can see that the rules are not as clear as they might seem, and we haven't even mention leap seconds for example.

The ctime library

C++ has two libraries for working with date and time. The first is ctime, which C++ inherited from C.
