Write a program that reads and prints a joke and its punch line from two different files. The first file contains a joke, but not its punch line.

The second file has the punch line as its last line, preceded by "garbage." The main function of your program should open the two files and then call two functions, passing each one the file it needs.

The first function should read and display each line in the file it is passed (the joke file).

The second function should display only the last line of the file it is passed (the punch line file). It should find this line by seeking to the end of the file and then backing up to the beginning of the last line.

Data to test your program can be found in the joke.txt and punchline.txt files.

To display the final line in a file, you need to find it by going to the end of the file and then

backing up a character at a time until it reaches the beginning of the last line. For example,

// Go to the end of the file.
infile.seekg(0, ios::end);

// Move backwards to beginning of the
// final char in the file and read it in
infile.seekg(-1, ios::cur);
ch = infile.get();

Then use while loop to back up until we find a newline. It is where the last sentence starts.

The joke.txt and punchline.txt are attached. You need to save them with the same folder as .cpp file in your project for testing your codes without specifying directory path.

To test the executable, save the exe, joke.txt and puchline.txt in a same folder. So you do not need to specify directory path for txt files.
