Unexpected response code representation

[thuanpv]

Hi @alan32liu

Last week you asked the following question

/* TOASK:
* 1s. using id 410 works, but changing it to 010 will not print out 8 instead
* Similarly, 020 becomes 16
* How does it become octal?
*/

I have checked your implementation of the append_child function (its signature is: TreeNode * append_child(TreeNode * tree_node, int child_response_code, enum node_colour colour)). If you pass "010", C treats it as an octal number and hence its decimal value is 8. Similarly 020 -> 16, 030 -> 24 and so on. I think you just need to pass decimal numbers and it should be fine.

Please see this to know more about octal numbers in C: https://www.includehelp.com/c/octal-literals.aspx

Thanks! I suppose this won't affect us then.

Yes, it doesn't.
