what is the difference between these two declarations

[Guybrush Threepwood]

Hi,
I was always wondering if there is any difference between

void someFunction(int,int)

and

void someFunction(int A, int B)

is there?

No difference.

No difference.

....assuming they're declarations and the OP simply omitted the semicolons
inadvertently. If they're the first line of function /definitions/,
however, there would certainly be a difference (in the first case, there'd
be no way to access the parameters.)

None from the language perspective. However, using (meaningful)
parameter names in a prototype can aid clarity.

On the other hand, with some compilers not using parameter names can
suppress "unused parameter" warning messages.

The first can only be a declaration.
The second could be the beginning of a definition.

Both can be declarations (and that's /all/ they'd be if you added a
semicolon), and both can be the beginning of function definitions. There'd
just be no way to get to the parameters in the first case.

There's even a common and reasonable use for a declaration and definition
with no
parameter name: operator++(int) - the post increment operator

Sure. I use the mechanism in at least three different places in each
version of my InitUtil library:

In those cases, template parameters are only mined for their type
information.
