Just use awk:

To be able to run system() function call in C in an embedded system, you need to know several things first:

• system() calls the user shell with the string passed as argument as a parameter. Are you running an operating system at all? A shell is normally an operating system component, and it is not normally present in many embedded systems.
• system() requires /bin/sh normally to work. To run ls, you need in adition to have it (the ls command) installed.

You don't say what operating system you have in your Raspberry pi pico, but I'm afraid it is not linux (or any unix flavour) so probably all of this is forbidden to you.

Normally, the requirements to have a unix like environment in a small system impede to use a high technology operating system in such systems. Linux requires large amoutns of memory (as there are in the normal raspberry pi, but not in the small versions), a large capacity storage system (bein a usb disk, flash memory card, etc. but normally several Gb for a minimum installation)

In your case, 264kb of ram are very small to have a non-mmu handled microprocessor, capable of addressing virtual memory spaces. Also 2Mb of flash gives you to write large programs, but not to install an operating system like linux.

Had you an emulator of system() you should be able to run other programs, but how? A raspberry pi pico has space to run just one program (the one you write to the flash and nothing else) Even if you write a kernel of a multitasking operating system, you would lack space to run filesystem stored programs, as you normally have limited access to the flash where programs are installed.

You have to use the START command instead of CALL command. (Documentation)

You can do like this :

Using instead of {{myvar}} solved it. I am not sure if there is a better solution

Two things.

(pivot - (pal_offset + 1) >= 0) will always be true, because pivot is an unsigned type, so the entire expression will be unsigned.

In the while loop inside that if, when pivot == pal_offset (which can happen with an odd length string) you will try to access s[-1], which is illegal (and a possible source of the runtime error you're getting).

Calling ducky.hatchedEgg (I guess you mean this instead of Bird.hatchedEgg) directly won't give you any result (undefined to be precise). That's the whole point of the example i.e the private variables are not accessible directly from outside. They are accessed by a method which in turn could be/could not be exposed to outside. Security comes from that.

Update I re-read the question again and what you're doing is this: You're attaching a property hatchedEgg to Bird and setting a value to it.

Bird.hatchedEgg = 20

However, this hatchedEgg is NOT the same as let hatchedEgg = 10; that's originally defined within the function.

ducky.getHatchedEggCount(); will still give you 10. Bird.hatchedEgg will give you 20 as you're attaching a property hatchedEgg to object Bird which is NOT the same as hatchedEgg declared inside the function Bird.

Also, functions first-class object and you can add/remove properties to it just like you'd do with any other object. However, in the last post, I intentionally tried to make distinction between function Bird and object Bird, to make the things clear. It's just like saying, arrays are objects too. But you maintain a distiction in the conversations so as to simply the things. Anyway, updating this as I think that led to some sort of confusion.
