Transform a C++ program consisting of multiple source files and headers into a single self-contained source file without any external dependencies (except for standard system headers). Unused code is not included in the resulting file.
template <typename T>
class C;
template <typename T>
class D
{
static void f ();
template <typename>
friend class C;
};
template <typename T>
class C
{
public:
static void f ()
{
D<T>::f ();
}
};
int main ()
{
C<int>::f ();
}
Everything else is preserved but
template <typename>
friend class C;
gets removed which makes D<T> inaccessible from C<T>
Example:
