How to Read User Input Line by Line in Golang with Scanner

In Golang, the bufio.Scanner type is utilized for reading input data conveniently. It processes data from an io.Reader like standard input, breaking it into tokens—typically lines of text—using a customizable split function. The default tokenizer splits the input on new lines, making it ideal for reading successive lines of user input or file data.

This Go code demonstrates reading multiple lines of input from a user using bufio.Scanner. It continues reading until the user types 'STOP', showcasing error handling and string comparison.
