make_set

Author: Cynthia Lee (on 2016/11/03)

Write a function named make_set that creates a bit vector set from a given array of values (arguments are an array of int and its size, as int [] and int). Returns an unsigned short that represents a bit vector set of the values from the array. The bits in positions 1-9 of the returned result mark the set membership, the remaining bits are zeros.

Precondition: every number in the values array is the range 1-9. Assume the array size is correct. Implementation can assume client is responsible for meeting precondition.

For example, if the input is {5, 3, 7}, then make_set returns 168 (binary 0000000010101000 -- note bit positions 5, 3, and 7 are 1).

Function: Write a C function as described, not a complete program.
