Implicit Template Parameters

Question

The following code generates a compile error in Xcode:

template 
struct Foo
{
    Foo(T Value)
    {
    }
};

int main()
{
    Foo MyFoo(123);         


        

Answer 1

It's not a bug, it's non-existing feature. You have to fully specify class/structure template arguments during instantiation, always, the types are not inferred as they can be for function templates.
