2. Destructor #

Created Thursday 30 January 2020

How to destroy the tree?

• Process once done with deallocates memory after the program ends? The problem is memory deallocation while the program is runnning.
• When we write delete obj_name, the destructor is called first. Here memory is deallocated for the attributes. Any DS’s inside need to be cleared explicitly. Taught in OOPS 1.
• Works like post order traversal.
• Base case does not need to be passed explicitly. When we come out of the for loop, the memory pointed by this is deallcoated. Hence every TreeNode is deallocated.
• Used the destructor recursively.

MashaAllah, we had created this recursive destructor at the first time when we created the TreeNode class. Congrats on the new skill 👍️.

Same as Ankush sir.
