In ex. 16, We are overriding the file, if it exists, otherwise create new one and open it for writing. Then my question is What is the significance of using truncate there after opening it in write mode? |

You are right, we do not need to use truncate when opening a file in w mode. In that mode the file is automatically truncated. I think this exercise uses truncate and then adds a point in the extra credit if the participant finds out whether truncate is needed. |
