Man, the quality of content is such, that it could be behind a paywall. Thanks for sharing it freely!

Thanks for the tutorial!
For completeness: Accessing a memory area (reading or writing) that has been freed by free is "undefined behavior".
This must not be done under any circumstances and leads to errors that are difficult to find. Even if you use another pointer for it (i.e. copy the memory address).

it happened again, in mine if I free(password), when i iterate print other_ptr it does not show the original password (it prints gibberish).
but if I don't free(password) then yeah I can see the password when I iterate print other_ptr.

This made me wonder has there been an update in terms of memory safety in the most recent C version?

In my case the password was not there anymore. Is it possible that my system or compiler is re-writing this memory space?

I copied and pasted the same code but it doesn't print the password after free() ?!

hi, if free() does not clear the memory, why we use it exactly, I do not get

So how do you properly clear the memory since free doesn't?
