Yes, it will eliminate the warnings, but it won't compile.  I think you
mean

	void funcname(
	  int x,
	  int y,
	  int z )
	{
	  x,y; // this will eliminate the "not used" warnings

	  printf( "%d", z );

	}

but it's the wrong way to do it.  (It's also a bear of a way to format
code.)

The right way is to use the language as it is meant to be used:

	void
	funcname( int, int, int z )
	{
		cout << z;
	}

(Note that we also get rid of the incompletely type-checked  printf() .)
What if you need the `documentation' value of the  x  and  y ?  You can
always place a prototype in front of the function:

	void funcname( int x, int y, int z );

	void
	funcname( int, int, int z )
	{
			. . .
