Using Variadic Templates cleanly - When one comes across examples for variadic templates, almost always lucky: the author correctly used zero // arguments instead of one as the base-case,

Variadic templates in C++ - Variadic templates are written just the way you'd write recursive code - you need a base case (the adder(T v) declaration above) and a general case which "recurses" [1]. The recursion itself happens in the call adder(args).

Why do I need a base case for Variadic Template even when I pass - Regardless of how many arguments you pass to your Variadic(T t, Args args), you're always compiling an unconditional function call to

Variadic template - In computer programming, variadic templates are templates that take a variable number of base case void printf(const char *s) { while (*s) { if (*s == '%') { if (*(s + 1) == '%') ++s; else throw std::runtime_error("invalid format string: missing

C++ Generics: Meta-Programming and Variadic Templates -- Visual - The first template is the two-argument base case. The second argument becomes the first one's best friend, and is also returned. The second template is a general case of the function template. Once again I use the variadic notation, as the number of arguments won't be known until instantiation.
