HW9: Counting Commoners

Given the following type definition,

typedef struct {
	char	name[40];
	int	value;
} NameValue;

(Note: A string is stored in the name array.)

which is stored in a file nv.h,
write a function, nv_countCommon(), that recieves 4 arguments:

	* an array of NameValue elements
	* a count of the number of elements in the array
	* a second array of NameValue elements
	* a count of the number of elements in the second array

The function returns the number of elements in the first array that
have the same name as an element in the second array (value is ignored
in this function).

You may assume that in a given array, all names are unique.

(ASIDE: Please note that the design of the above type is inadequate:
in general we will not use static arrays to store names; we do so
here only because we have not developed all the tools yet to do it
a better way.)

The file containing this function should be called:
	nv_countCommmon.c

It should #include the file nv.h.

Besides writing this file, you will need to test it. The basic idea is 
that to test this function you should create a separate file 
(test_nv_countCommon.c) that contains a main() function and calls 
nv_countCommon().  By feeding nv_countCommon() various array 
combinations, you can verify that it is correct, or at least gain 
confidence in its correctness.
