Create a file called input9B.txt and type (or copy) the following text exactly as it appears below into that file.

The problem is that the extraction operator does not read the white spaces, i.e., it skips blank spaces, tabs (\t), and new lines (\n).

In order to read and write the entire text with correct spacing, we will use a member function with the input stream. The get(c) function, where c is a character, allows us to read all characters from the file one character at a time. So to fix the above program we could simply use this function instead of the extraction operator. The member function eof() can be used with a stream of input type to determine the endof-file. This function returns true when the end of the input file is reached. Thus, it can be used in a while loop to control the looping process. In general, you need to read one character before you check to see if the end of the file is reached. 4 Now, modify the above program by using the get() member function instead of the extraction operator (i.e., >>) as well as the eof() member function to read until the end of the file. But instead out displaying the contents to the terminal, modify the program so that it writes to whatever output file is specified by the user using the put() function. To do this, you will need to modify the program so that it prompts the user for the filenames for two streams, one for the input and the other for the output. Note that you can remove the two cout statements in main with the "***" as these lines do not need to be written to the file. When testing, do not overwrite the input file input9B.txt, but instead use out9B.txt.
