- 1You should adjust the pointers in the list before calling free, if you call free before you've finished with the pointer then you will corrupt memory. Option 1, save test to another, reassign, then free saved pointer.SPlatten– SPlatten2019-11-26 07:44:08 +00:00Commented Nov 26, 2019 at 7:44
- 2Option 1 is plain wrong. Dereferencing a pointer once it has bee freen leads tol undefined behaviour which includes "apparently working fine"..Jabberwocky– Jabberwocky2019-11-26 07:45:57 +00:00Commented Nov 26, 2019 at 7:45
- From your explanation, I gather you don't understand why option 2 is correct ? It does not "start with the Second Node" as you think. I recommend drawing it out while following the code. Also, refer to this question for an explanation : C: How to free nodes in the linked list?.Sander De Dycker– Sander De Dycker2019-11-26 07:51:24 +00:00Commented Nov 26, 2019 at 7:51

def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
