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.

 

[Leor Zolman]

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.

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

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.

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
