...ally, that's not quite right: C++ doesn't work on containers but rather on ranges that are defined by two iterators, pointing to the beginning and behind the end of the container. Thus, the whole content is circumscribed by the iterators: begin <= elements < end.
Using iterators instead of co...

}
// if the program gets here, no port in the range was found

How do I get a Cron like scheduler in Python? [closed]
... = CronTab(
Event(perform_backup, 0, 2, dow=6 ),
Event(purge_temps, 0, range(9,18,2), dow=range(0,5))
)
This way you get the full power of Python's argument mechanics (mixing positional and keyword args, and can use symbolic names for names of weeks and months)
The CronTab class would be defi...
What does [ N … M ] mean in C aggregate initializers?

It is initialization using Designated Initializers.
The range based initialization is a gnu gcc extension.
To initialize a range of elements to the same value, write [first ... last] = value. This is a GNU extension. For example,

Conveniently Declaring Compile-Time Strings in C++
... constexpr char x = world[5]; // Does not compile because index is out of range!
}
It doesn't get much cooler than compile-time range checking!
Both the use, and the implementation, is free of macros. And there is no artificial limit on string size. I'd post the implementation here, but I'm re...
