sth in its definition.
however, the following code compile with Gcc/VC 7.1
int func (void) {}
why? | c********e

It's never a strong type language which an OOL should be. | r****y
发帖数: 26819 | 4 If you use the return value, such like
cout << func();
compiler will report error.
If func() is a global function, VC compiler will report error too.
For member function, ok if return value not used.
