Write a program ( lab7.cpp ) that gives and takes advice on program writing. The program starts by writing a piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends. The next person to run the program receives the advice given by the person who last ran the program. The advice is kept in a file, and the contents of the file change after each run of the program. You can use your editor to enter the initial piece of advice in the file so that the first person who runs the program receives some advice. Allow the user to type in advice of any length so that it can be any number of lines long. The user is told to end his or her advice by pressing the Return key two times. Your program can then test to see that it has reached the end of the input by checking to see when it reads two consecutive occurrences of the character . An example run of the program is shown below:

Hints: - You need to look at each character as it is read to see if it is . So you need to use cin.get() . And you should then use out.put() to match, where out is a stream connected to the file. - Be sure to open the file as an ifstream, read it and print it to the display, then close it; then reopen the same file as an ofstream so you can write the new advice to the same file.
