Name _______________________					Section _____

A. On the back of this sheet, write a subroutine called countzero which
counts all of the used elements of a real array which are zero and sets
the last parameter to that count.

Assume you have declarations such as
	type	realara=array[1..100] of real;
	var
		data:realara;
		size: integer;
		count: real;

Then invoking your procedure with

	size := 90;
	countzero(data, size, count);
	writeln('The number of zero elements in the array is ', count);

should print out the number of zeros in the first 90 elements of the array
data.  Make the order of your parameters match this example.  JUST WRITE THE
PROCEDURE, DON'T REPEAT THE DECLARATIONS SHOWN ABOVE (just use them).
--------------------------------------------------------------------------
For the next two questions, assume that we have a database with the following
entries.  Assume that you are dealing with a program of the type discussed in
the text or covered in the lectures.

Ford	4dr	Clarke	green
Chevy	2dr	Herbert	green
Ford	4dr	Hogan	blue
Chevy	4dr	Anthony	green
Ford	van	Niven	green
Chevy	2dr	Niven	blue
Dodge	van	Gibson	blue

B. Assume that the following query was typed into this program:

Ford
?
?
green

What output is produced?




C. Assume that the following query was typed into this program:

?
van
?
?

What output is produced?
