Compiler Warning (level 1) C4183

'identifier': missing return type; assumed to be a member function returning 'int'

The inline definition of a member function in a class or a structure does not have a return type. This member function is assumed to have a default return type of int.

The following sample generates C4183:

// C4183.cpp
// compile with: /W1 /c
#pragma warning(disable : 4430)
class MyClass1;
class MyClass2 {
   MyClass1() {};   // C4183
