In many programming scenarios, it's necessary to read input until the end of file (EOF) is reached. This is a common task when dealing with file input or user input from the console. The problem context here is to read lines of input and print each line along with its line number until EOF is reached.

The solution uses a Scanner object to read input. It initializes a counter 'i' to 1. Then, it enters a while loop that continues as long as there is more input (sc.hasNext()). Inside the loop, it prints the current line number (i) and the line of input, and then increments 'i'. The loop ends when there is no more input, i.e., when EOF is reached.
