What are some C++14 templates I can use in my project?

C++14 introduced several features that enhance template programming. You can use features like variable templates, generic lambdas, and more. Would you like examples of each?

Yes, please provide examples of variable templates and generic lambdas.

Sure! A variable template example is: template <typename T> constexpr T pi = T(3.1415926535897932385); For generic lambdas, you can write: auto lambda = [](auto x) { return x + x; };.

How do I use these in a function?

You can use the variable template in a function like this: template <typename T> T area(T radius) { return pi<T> * radius * radius; } And call the lambda like this: auto result = lambda(5);.
