Compiler Error C3747

missing default type parameter : parameter param

Generic or template parameters with default values cannot be followed in the parameter list by parameters that do not have default values.

The following sample generates C3747:

// C3747.cpp
template <class T1 = int, class T2>   // C3747
struct MyStruct {};

Possible resolution:

// C3747b.cpp
// compile with: /c
template <class T1, class T2 = int>
struct MyStruct {};
