Look at the function prototype for 'f'. Does it say anything about taking struct A as a parameter ? > Visual C++ 8.0 does and says 'cannot convert to 'int'' in spite of the > standard. The function 'f' takes an 'int' as its only parameter. What do you expect Visual C++ 8.0 to say ? A friend function does not have a hidden 'this' in its function prototype. I think you are confused by what 'friend' means in C++. --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
