3.6 multable.cpp

        Write program to display a multiplication table. The size of
        the table is controlled using one value SIZE. Tip: to make the
        output evenly spaced, utilize function printf(). You can
	assume that the the SIZE is in range 1..9[1]

            int size = 9;

        Output:

             * |  1  2  3  4  5  6  7  8  9
            -------------------------------
             1 |  1  2  3  4  5  6  7  8  9
             2 |  2  4  6  8 10 12 14 16 18
             3 |  3  6  9 12 15 18 21 24 27
             4 |  4  8 12 16 20 24 28 32 36
             5 |  5 10 15 20 25 30 35 40 45
             6 |  6 12 18 24 30 36 42 48 54
             7 |  7 14 21 28 35 42 49 56 63
             8 |  8 16 24 32 40 48 56 64 72
             9 |  9 18 27 36 45 54 63 72 81

	[1] If the SIZE would exceed 9, the requirements to display
	evenly spaces values would change dynamically from row to row
	and this is not easy to solve. E.g.

	     10 x 15 => value 150 would require 3 digit display area
	     99 x 55 => values 5445 would require 4 digit display area
