C++ Mid-Block Declarations	    Bob Walton, 7/16/96


C++ permits you to write:


	{
		int x;

		x = 8;

		int y;

		y = 9;
	}

and treats it as if you had written:

	{
		int x;

		x = 8;
	    {
		int y;

		y = 9;
	    }
	}

In other words, C++ is nice enough to put in the braces
for you.

However there is one difference between putting-in-the-
braces and C++.  C++ will not permit you to declare the
SAME variable twice in one block.  Thus

	{
		int x;

		x = 8;

		int x;

		x = 9;
	}

is illegal C++ but

	{
		int x;

		x = 8;
	    {
		int x;

		x = 9;
	    }
	}

is legal C or C++.
