the difference my child is! that int setDate(void) returns to the calling function a integer but does not require any arguments thats why (void)-(However you could leave void out of the '()' becuase its unnessesary).
and void setDate(int) doesnt return anything but needs an integer as an argument.
this comes from some german geek. hahaha

My guess would be that the author wanted setDate to both set the date and return the current date if no new date is given:
I think it would be better to have the date returned and a default argument to determine if the date should be changed:Code:int setDate(void) { return date; } void setDate(int newDate) { date = newDate; }
Code:int setDate(int newDate=-1) { if (newDate != -1) date = newDate; return date; }

Default arguments aren't any more confusing than function overloading, which wasn't even touched on earlier in the thread. If you're going to criticize, at least do so fairly for everyone.

I'd prefer Get/Set:or something that makes it look like a property:Code:int getDate() { return date; } void setDate(int newDate) { date = newDate; }I doubt you'd want to call a method setDate and have it actually get the date.Code:int Date() { return date; } void Date(int newDate) { date = newDate; }
