Discussion
The number of distinct nodes the following struct declaration can point to is
struct node
{
struct node *left;
struct node *centre;
struct node *right;
};
Answer: A
Correct answer: All of the above
The structure holds three pointers, so at most it points to three nodes - but nothing requires them to be different. Two of the pointers may hold the same address, or all three may, so the number of distinct nodes reached may be 1, 2 or 3. All the counts offered are possible.
