Sort three

Write a procedure

        void sort3(int& a, int& b, int& c);

to sort @a@, @b@ and @c@ in nondecreasing order. For instance, if called
with @a@  = 7, @b@  = −3 and @c@  = 1, the values after the call must be
@a@  = −3, @b@  = 1 and @c@  = 7.

Observation

You only need to submit the required procedure; your main program will
be ignored.
