Simple example using variadic templates

variadic_templates.cpp

#include <string>
#include <iostream>
#include <typeinfo>

template <typename T>
void f(T t)
{
    std::cout << typeid(t).name() << ":" << t << std::endl;
}

template <typename T, typename ...N>
void f(T t, N... n)
{
    std::cout << typeid(t).name() << ":" << t << " ";
    f(n...);
}

void g()
{
    std::cout << std::endl;
}

template <typename T, typename ...N>
void g(T t, N... n)
{
    std::cout << typeid(t).name() << ":" << t << " ";
    g(n...);
}

int main()
{
    f(2);
    f(1, 2, 3, 4);
    f("array");
    f(333, "foobar");
    f(4.5, std::string("text"), 884477ul);

    std::cout << "======================" << std::endl;

    g(2);
    g(1, 2, 3, 4);
    g("array");
    g(333, "foobar");
    g(4.5, std::string("text"), 884477ul);

    return 0;
}
