I’m working on understanding exit codes in C++. I noticed that if a C++ program returns the value 4294967296 (which is beyond the range of a 32-bit integer), the exit code is 255. Given that 32-bit integers typically range from -2147483648 to 2147483647, why does this specific return value produce an exit code of 255?

I would appreciate any insights into how integer representation and memory management cause this behavior.

Below is the video and pic link showing the error:

I have searched on Google and various platforms, but got limited with information available on the Internet. It shows the range is only because of your OS. Another video in my repo will show you I used the bash script and printed through the whole range.
