Variadic Templates

Variadic templates, introduced in C++11, provide a way to create templates that can accept a variable number of arguments. Using the ellipsis (...) notation, you can define parameter packs that represent zero or more arguments of potentially different types. This allows for the creation of functions and classes that can operate on varying numbers of inputs, enhancing code flexibility and reusability, as demonstrated by use cases such as summing multiple arguments or creating tuple-like structures.
