            According to this documentation, the function fgets takes 3 parameters, in this order:

            1. a pointer to the memory buffer to write to
            2. the size of the memory buffer
            3. the FILE * stream to read from, for example stdin

            The array newStr is not a FILE * stream. Therefore, it is not valid as a third parameter.

            If you do not intend to read from a FILE * stream (such as stdin or a file opened with fopen), then you should not be using the function fgets.

            Well while is what you use when you don't know yet how many steps it will take and since that is kind of baked into the logic of finding the conjecture for a value there is not really a way around it. I personally think there is nothing bad about using while loops.

            You can still make the code a bit more compact and readable while keeping the while loop, e.g. like this:

            As the lines have different lengths, I would refrain from using FuncAnimation and instead use the interactive plotting with plt.ion(). I tried to mainly keep your structure, but introduced some changes.
            First, I got rid of the x-range lists. This is implicit information of your list l, so we don't have to collect it separately.
            Second, as the graph does not auto-update when plotting outside values, we have to collect the maximum values for the x and y axes, so we know when we have to update the graph limits.
            Finally, we plot each line object once, then update its values in each new iteration. An implementation could then look like this:

            C++ Dangling pointer issue
            Asked 2022-Mar-03 at 10:50

            I am using the Raylib GUI framework for a project that displays all the nodes within an iteration of the Collatz Conjecture. In my program, I have a class for a Node object that acts simply as a circle with a labelled number. The variable text in my draw method, however, has an issue; C26815: The pointer is dangling because it points at a temporary instance which was destroyed. I'm new to C++ and don't have access to any books to teach me at the moment, hence I'm not entirely sure what a "dangling" pointer is or what it means, but I'm fairly certain it's the reason I can't display any text on my nodes. Here's my Node class:

            You can use an extra variable, here i, to print lables.

            Also, I removed end parameter so that it print line by line. In addition, I used f-string for printing format. For more detail, please see https://realpython.com/python-f-strings/

            Collatz conjecture function in Python3 calling itself when being assigned to a variable
            Asked 2022-Jan-30 at 07:01

            I'm reading the book "Automate the boring stuff" by Al Sweigart to start learning Python (it is free online, so you can check it if you're interested, or you think that it would help solve my problem). And by the end of Chapter 3, you are given an exercise, creating a program that can execute the Collatz Conjecture. I've successfully created a function that takes an input integer and divides it by 2 or multiplies it by 3 and adds 1 for even and odd numbers, respectively.

            The issue comes, when I try to take the value returned by the function, and assign it to a variable(so I can make a loop that will stop when the number gets to one), it instead calls the function, and when I try to use the function inside a while loop it returns a None value.

            I tried comparing it to other program that simulates a magic 8-ball, because the way I made the way I made the Collatz program is very similar to the 8-ball, but somehow the 8-ball does work, and the Collatz doesn't, and since I'm currently out of ideas, I ask you if you can notice any typos in my code that may indicate why this is happening.

            I thank you in advance for your time and effort. PS: don't forget to drink some water, it is good for you <3

            You have unused variables, and you need to define a return value for collatz().

            Right now, you define a variable newNumber, but never use it anywhere in your code. You should be updating startNumber instead (renamed to num below for readability). You also need to define a return value for collatz(); otherwise, it will return None, which isn’t what the question asks for.

            Here’s a solution which resolves these issues.
