Capturing SIGINT Signal for Graceful Shutdown Using "Defer" Approach

Handling user interruptions is crucial for maintaining a clean application shutdown. One common scenario involves capturing the SIGINT signal (Ctrl C) to perform cleanup tasks before exiting.

To capture SIGINT, you can utilize the os/signal package in Golang. Here's how you can do it:

When you press Ctrl C, the SIGINT signal is sent to the program. The main function captures this signal through the channel c. The cleanup function is scheduled to run before the program exits, thanks to the defer keyword. This ensures that the cleanup tasks are executed after any outstanding operations in the loop.

You can customize the behavior of the cleanup function to suit your application's needs. For instance, you can use it to save unsaved data, close connections, or perform any other necessary tasks.
