Simple C++ output exercises: cout, <<, endl and \n

Now that we've learned how to display simple C ++ outputs using the cout command, let's practice a little more.
I want to see you trying, until you can, solve the exercises below.

C++ Exercises

1. Phrase on screen - Create a program that displays the phrase "The first program we never forget!"

2. Etiquette - Design a program that writes your full name on the first line, your address on the second, and zip code and phone number on the third, using endl.

3. Repeat the previous program, now using \ n instead of endl. Can you do everything in one cout command only? Try it.

4. Lyrics - Make a program that displays on the screen a lyrics you like (forbidden Justin Bieber lyrics).

5. Message - Write a message to a person you like. Implement a program that prints this message, prints it out, and sends it to this person. Say it was a virus that a hacker installed on your computer.

6. To the site - Make a program that shows on screen what you want to do using your C ++ skills.

7. Square - Write a program that shows the following figure:

XXXXX
X         X
X         X

8. Gradebook - You were hired by a school to do the student report card system. As a first step, write a script that produces the following output:
