Pass appropriate amount and type of arguments to a function

I'm wondering if such a thing is even possible in C++11, passing appropriate amount and type of arguments to a function when for example you have:

template <typename R, typename ... Types> 
constexpr std::integral_constant<unsigned, sizeof ...(Types)> getArgumentCount( R(*f)(Types ...))
{
   return std::integral_constant<unsigned, sizeof ...(Types)>{};
}

void foo(std::string first, double second, std::string third);
void bar(std::string first, std::string second);
void baz(std::string first, int c);

void passArgs(std::vector<std::string> arguments)
{
    //Get arguments count for function foo, do the same for the others
    size_t foo_count = decltype(getArgumentCount(foo))::value;
    //Here pass appropriate amount of arguments to foo,bar and baz and 
    //convert to appropriate type using for example std::stoi and 
    //std::stod when the argument is int or double
    Magic(foo,arguments,foo_count);
}

int main()
{


}

Thank you in advance.
