func(void) or func() ?

Having never read a C++ book until after I learnt the language :eek: it just made sense to me that if you have to specify that a method returns void, it was more consistant to specify it for methods which take no parameters also. :) As it's not mandated either way by the language spec, it really comes down to personal style. It is notable though that if you try to declare a C# method with parameter "void" the compiler barfs at you..which only goes to reinforce one of your earlier sigs. ;) Anna :rose: "Be yourself - not what others think you should be"

Since upgrading to VS.NET I have noticed that any classes I add using the "Add New Class" wizard will use
voidfor functions with no params (such as constructors/destructors). Personally, I haven't bothered doing this sonce my C days, so my question is - are there any benefits tovoid? What do you prefer for your member functions:void SomeFunc(void);orvoid SomeFunc();
When I am king, you will be first against the wall.
in C#,
void SomeFunc(void)is not a legal syntax. A parameterless function must be declaredvoid SomeFunc(). It drives me crazy, especially because I like the first way to explicitly say "this function takes no parameters". Oh well. Marc Help! I'm an AI running around in someone's f*cked up universe simulator. -

Stroustrup had an article in CUJ a couple of months ago on the subject "C and C++ compatibility", he mentions the empty parameter list vs. the void parameter list and one of them is supposed to mean that the function may take a parameter of any type, but I can't remember which...

From the C++ standard: If the parameterdeclarationclause is empty, the function takes no arguments. The parameter list (void) is equivalent to the empty parameter list. Tim Smith I'm going to patent thought. I have yet to see any prior art.

main function can be declared as returning void or int both in C and C++. If you declare it as int, you let your program return a value (typically an error code) that operating system or calling process can use.

int main()

}
There are only 10 kind of people in the world: those who understand binary and those who don't.

I don't care, I decided to use only the following prototype for all of my C functions, and use casting till death!
void someFunc( const void * const * const args )
{}
and deal with it later ! Max.

:-) Well good for you! But shouldn't you be returning
void*? Regards, Alvaro
