I'm trying to work with large numbers (~10^14), and I need to be able to store them and iterate over loops of that length. ie. n=SOME_BIG_NUMBER do i=n,1,-1 I've tried the usual star notation, kind=8 etc. but nothing seemed to work. Then I checked the huge(i) functions, and the code: program inttest print *,huge(1) print *,huge...

I have a do/while loop that goes over database rows. Because it runs many days at the time processing 100000s of rows, memory consumption is important to keep in check or it will crash. Right now every iteration adds about 4kb to script's memory usage. I'm using memory_get_usage() to monitor the usage. I unset every variable used in the...

He added, though, that I would find several cases of break st...

How can one loop a command/program in a Unix shell without writing the loop into a script or other application. For example, I wrote a script that outputs a light sensor value but I'm still testing it right now so I want it run it in a loop by running the executable repeatedly. Maybe I'd also like to just run "ls" or "df" in a loop. I...
I need to get populator to build me an order history such that: The record has a start_date and end_date Each record specifies a period between 0 and 5 years Events are pretty much consecutive (meaning the end date of record n affects the start date of record n+1) There can be gaps between events (periods of no orders) but no overlaps ...
For efficiency reasons, I always avoid writing loops like this: for(std::size_t i = 0; i < vec.size(); ++i) { ... } where vec is an STL container. Instead, I either do const std::size_t vec_size = vec.size(); for(std::size_t i = 0; i < vec_size; ++i) { ... } or use the container iterators. But how bad is the first solution really...
