In C++17, fold expression is available, so to print arguments, we could usehaving the output 1test5.6
I am new to template programming and I have two questions...Hopefully someone can help me. I am trying to use variadic templates to generate a new input to another variadic template. In other words, I have a class
When looking at std::visit() page in cppreference, https://en.cppreference.com/w/cpp/utility/variant/visit, I encountered the code I can't make sense of...
Given:and:How should I write that static_assert to be as cheap as possible in compile-time?I'm using C++17.
I've written (in c++11) a variadic template constexpr function which calculates max sizeof of the parameter types, e.g.:
I have several vectors of either ints or doubles:I need to process the cartesian product of each vector:
Today I've discovered that I don't understand the C++ constructor precedence rules.Please, see the following template struct wrapper
In my code, I use variadic template functions for the logging purpose. But when I use std::endl as parameter, I get the following compiler error:
