This program demonstrates basic file handling, writing and reading data from a text file.

Explanation:

• It first asks the user to enter their name.

• The entered name is written to a file named user.txt using an output file stream.

• Then, it reopens the same file in read mode and retrieves the saved name.

• Finally, it displays the name read from the file on the screen.

• If there’s an issue opening the file for writing or reading, an error message is shown.
