/* If bitwise AND, OR, and exclusive OR are to cause
trouble, they will probably do so when they are used in
an unusual context. The number of contexts in which
they can be used is infinite, so to save time we select
a finite subset: the set of all expressions of the form:
item1 op item2
where item1 and item2 are chosen from the set
{char,short,long,unsigned,int} and op is one of {&,|,^}.
We will use 12 and 10 as values for the items, as these
values will fit into all data types on just about any
imaginable machine, and the results after performing the
bitwise operations on them are distinct for each operation,
i.e.,
12 | 10 -> 1100 | 1010 -> 1110 -> 14
12 ^ 10 -> 1100 ^ 1010 -> 0110 -> 6
12 & 10 -> 1100 & 1010 -> 1000 -> 8
There are 75 such combinations:
