问题 I was trying to understand helper functions in C++ from The C++ Programming Language by Bjarne Stroustrup . But the book hasn't explained anything about it and the purpose of using it in classes.

I have got the gist of it but still unclear about what is the real purpose of helper functions, when should I use them and on the whole, what are helper functions? 回答1: "helper function" is not a term that you would find in a standard, neither it has an

Here: choose :: [a] -> a and choosep :: a -> [a] -> a -- BTW, not a _p_redicate Is the "p" suffix for the helper recursive function choosep a known naming convention? Perhaps it comes from functional

问题 These functions may be hard to fit into a specific class, what's the best practice to deal with them? 回答1: I suppose you mean methods instead of functions? You should really imagine the word static doesn't exist in Java world, there really isn't a case where static would actually do you anything good in the long run. I'm actually currently facing a similar problem, I have a whole bunch of API methods I want to give out for users to meddle with but I want to hide the actual methods underneath

The problem of course is that if I just cram everything into one class,

问题 I have a helper function that turns minutes into hours/mins. I currently have it in my layout.cshtml but each page cannot see the function. Where should I put the helper function such that every page can see it? @helper DisplayElapsedTime(int timeInMins){ String timeStr = ""; if (timeInMins >= 60) { int hours = timeInMins/60; timeInMins -= hours * 60; timeStr = hours + "h "; } if (timeInMins > 0){ timeStr += timeInMins + "m"; } @timeStr; } 回答1: You should put it into the App_Code folder.
