A C program may also use the exit() function specifying the integer status or exit macro as the first parameter. The return value from main is passed to the exit function, which for values zero, EXIT_SUCCESS or EXIT_FAILURE may translate it to "an implementation defined form" of successful termination or unsuccessful termination. [citation needed]
The exit operation typically performs clean-up operations within the process space before returning control back to the operating system. Some systems and programming languages allow user subroutines to be registered so that they are invoked at program termination before the process actually terminates for good.
Python uses sys.argv, e.g.: import sys for arg in sys . argv : print arg Python also has a module called argparse in the standard library for parsing command-line arguments.
A loop invariant is an assertion which must be true before the first loop iteration and remain true after each iteration. This implies that when a loop terminates correctly, both the exit condition and the loop invariant are satisfied. Loop invariants are used to monitor specific properties of a loop during successive iterations.
The language provides loop control similar to many other languages. A loop begins with do and ends with end. In the related NetRexx, the keyword loop is used instead of do, and ooRexx treats loop and do the same. A loop is aborted (early exit) via leave and short-circuited (continued) via iterate.

Windows Subsystem for Linux (WSL) is a feature of Microsoft Windows that allows for using a Linux environment without the need for a separate virtual machine or dual booting. WSL is installed by default in Windows 11. [2] In Windows 10, it can be installed either by joining the Windows Insider program or manually via Microsoft Store or Winget. [3]
In computer programming, an infinite loop (or endless loop) [1] [2] is a sequence of instructions that, as written, will continue endlessly, unless an external intervention occurs, such as turning off power via a switch or pulling a plug.
