What does the endl function in iostreams do?

Ends the line and outputs a newline character
Closes the file stream
Encodes the line
Erases the previous line

The correct answer is: Ends the line and outputs a newline character

The endl function in iostreams ends the current line and outputs a newline character. This is useful for formatting output and ensuring that each line is on a separate line. Option B is incorrect because it refers to closing a file stream, which is done with the close() function. Option C is incorrect because encoding refers to converting character sets, not adding a newline. Option D is incorrect because erasing the previous line is not a function of the endl function.
