HW 11: Cells, Values, Addresses, and Indices

In this assignment, you are to write four functions:

	samecell()
	samevalue()
	indexcell()
	indexvalue()

(1) samecell() receives two parameters, both pointers to ints. It
    returns 1 if the parameters point to the same memory cell,
    (address in memory) otherwise it returns 0.

(2) samevalue() receives two parameters, both pointers to ints. It
    returns 1 if the parameters point to different memory cells,
    i.e. different addresses, that contain the same value, 
    otherwise it returns 0.

(3) indexcell() receives three parameters:
	an array of ints
	a count of the number of elements in the array
	a pointer to an int
    If the third parameter points to one of the elements
    in the array (that is, it points to an address in the
    array), then the the function returns the index
    of the element pointed to; otherwise -1 is returned.

(4) indexvalue() receives three parameters:
	an array of ints
	a count of the number of elements in the array
	a pointer to an int
    If the third parameter points to a memory cell whose
    value equals one of the array elements, then the the
    function returns the index of the first matching array
    element; otherwise -1 is returned.


The name of the file should be "CellValue.c" .  It should
contain ONLY the functions listed above.
