In the text, we say that after the merge sort splits the vector into two subvectors, it then sorts these two subvectors and merges them. Why might someone be puzzled by our statement that “it then sorts these two subvectors”?
What will be an ideal response?
In a sense, it does not really sort these two subvectors. It simply keeps splitting the original vector in half until it provides a one-element subvector, which is, of course, sorted. It then builds up the original two subvectors by merging these one-element vectors to form larger subvectors, which are then merged, and so on.

Write a void function called copy_to_screen that copies the contents of a file to the screen. The argument of the function is an ifstream object. Preconditions and postconditions follow: Preconditions: The stream argument for the function has been connected to a file with a call to the member function open. Postcondition: The contents of the file connected to the ifstream argument have been copied to the screen so that the screen is the same as the contents of the file. This function does not close the file.
