The following definition has proven to be very useful for me:Basically, the arguments pack folded on comma operator, allows to define several calls to a function taking an argument. For example:
I'd like to write a template function that iterates over a container of std::pair and returns a templated value with both types in the pair. I've gotten this to work for std::map as follows:
Is there a way to generate a templated function where there is an equal number of template params and function params (of the same type)?
I have an annoying scenario where I need to defer the initialization of some object state and allow the user to construct one on demand. E.g.
I want to write a function that accepts a variable number of string literals. If I was writing in C, I would have to write something like:
In C++ is it possible to define multiple methods based of the number of template parameters provided? Similar to how variadic functions work?
Consider the following code snippet:clang++ (trunk) successfully compiles the code with -std=c++17g++ (trunk) fails to compile with the following error:
I have a particular format that requires space delimited tokens with a final null terminator (the null is part of the output). I created a function to send a series of space delimited tokens to an output stream:
