Answer 1

At first glance, the function declaration for findPreSuc() does not look right. I think the ampersands (&) on the parameters should not be there.

Change this:
void findPreSuc( struct Node* root, struct Node* &pre, struct Node* &suc, int key)

To this:
void findPreSuc( struct Node* root, struct Node* pre, struct Node* suc, int key)

Remove #import <conio.h>, because you are not using any of the functions defined therein. Then you can also have it build and run here on SoloLearn.

Answer 5

Sooraj m, now I looked at it in depth and I see the need for more pointer syntax corrections. Here are the line numbers and corrected code.

14 void findPreSuc( struct Node* root, struct Node** pre, struct Node** suc, int key)

26 *pre = tmp ;

35 *suc = tmp ;

43 *suc = root ;

48 *pre = root ;

97 findPreSuc(root, &pre, &suc, key);

Try these changes. I think you will be very pleased with the outcome!
