Compilation Error on Recursive Variadic Template Function

Question

I\'ve prepared a simple variadic template test in Code::Blocks, but I\'m getting an error:

No matching function for call to \'OutputSizes()\'

Answer 1

Here's how you disambiguate the base case:

#include 
#include 

template 
void OutputSizes()
{
    std::cout << typeid(FirstDatatype).name() << ": " << sizeof(FirstDatatype) << std::endl;
}

template 
void OutputSizes()
{
    OutputSizes()
    OutputSizes();
}

int main()
{
    OutputSizes();
}
