I quite often encounter a problem of converting mostly optional settings-like object into strings or lists (e.g. into arguments for launching some external program). Usually I end up with imperative code similar to this:
I am trying to separate elements of a list into to further lists, one for the odd and one for even numbers.
I want the user to enter a number from 1 to 7. If the number is 1, print that it is a Monday. If the number is 2, print that it is Tuesday, etc.

I want to pass a dynamic size standard and of typename type array to a function.I can't figure out how to do it. Why can't I just accept a reference to the object array?
Consider this function template:This invocation works:This one doesn't:(gcc and clang both complain about too many arguments for foo)
When refining concepts, the way it is consistently done in the standard is to fully write out the concept being refined. For instance, in [concepts.integral], SignedIntegral refines Integral like so:
i simplified the problem as much as i could so here is the function in question:if i call the function with int-typing everything works fine, however, if i call it with a void-typed lambda it doesn't compile anymore.
This question already has an answer here:While doing a project I wrote this line, basically it decided whether or not to merge the current node based on how many children there are.
I am doing an assignment and my prof gave us this task as part of the assignment. I am still relatively new to C++ so any help. I created the function however I don't understand how he wants to return a blank string if nothing is found but return an...
