So you can think of a new line as being rolling the paper up so you're on a new line but a carriage return moves the cursor or moves that writing head all the way back to the left.

你们可以把换行想象成翻纸,把回车当做是将光标,移动到最左边。

If n is greater than zero, I decided I would say, "You picked a positive number, backslash n," so put the cursor on the next line, else if n was not less than zero, I say, "You picked a negative number, backslash n."

如果n比0大，我就决定来说：,“你选择了一个整数，反斜杠n“，所以你把光标,放在下一行，另外如果n不小于0，我说：,“你选择一个负数，反斜杠n“
