What Are Variadic Templates, and How Are They Used?

Variadic templates allow you to create functions or classes that accept a variable number of template parameters. They enable more flexible and generic code. Variadic templates are useful for creating functions that work with different numbers of arguments.

Example of variadic templates:

#include 

template 
void print(T arg) {
    std::cout << arg << std::endl;
}

template 
void print(T arg, Args... args) {
    std::cout << arg << " ";
    print(args...);
}

int main() {
    print(1, 2, 3.5, "hello");
    return 0;
}
