9. Change the representation of Person to have first_name and second_name instead of name. Make it an error not to supply both a first and a second name. Be sure to fix >> and << also. Test.

https://www.stroustrup.com/Programming/PPP2code/std_lib_facilities.h

Chapter 15 // Class Definition Drills

1. Define a struct Person containing a string name and an int age.
2. Define a variable of type Person , initialise it with "Goofy" and 63, and write it to the screen (cout).
3. Define an input (>>) and an output (<<) operator for Person; read in a Person from the keyboard (cin) and write it out to the screen (cout).
4. Give Person a constructor initialising name and age.
5. Make the representation of Person private, and provide const member functions name() and age() to read the name and age.
6. Modify >> and << to work with the redefined Person.
7. Modify the constructor to check that age is [0:150] and that name doesn't contain any of the characters ; : " ' [] * & ^ % $ # @ ! . Use error()  in case of error. Test.

Chapter 15 // Shape Function Graphing Drills 1, 2, 3, 4, 5, 6, 7, 8, 9 - Principles & Practice Using C++

In this exercise I am using Visual Studio 2017 and the graphics files found here:
https://github.com/l-paz91/principles-practice/tree/master/Graphics%20Files

Chapter 15 // Function Graphing Drills

1. Graph the function  double one(double x) {return 1;} in the range [-10,11] with (0,0) at (300,300) using 400 points and no scaling (in the window).
2. Change it to use x scale 20 and y scale 20.
3. From now on use that range, scale, etc. for all graphs.
4. Add double slope(double x) {return x/2;} to the window.
5. Label the slope with a Text "x/2" at a point just above its bottom left end point.
6. Add double square(double x) {return x*x;} to the window.
7. Add a cosine to the window (don't write a new function).
8. Make the cosine blue.
9. Write a function sloping_cos() that adds a cosine to slope() (as defined above) and add it to the window.

All of these functions can be found from section 15.2 to 15.3.2. If you have already followed along with the chapter you will have done them.

In this exercise I am using Visual Studio 2017 and the graphics files found here:
https://github.com/l-paz91/principles-practice/tree/master/Graphics%20Files

Chapter 15 // Function Graphing Drills

1. Make an empty 600-by-600 Window labeled "Function Graphs".
2. Note that you'll need to make a project with the properties specified in the "installation of FLTK" note from the course website.
3. You'll need to move Graph.cpp and Window.cpp into your project.
4. Add an x axis and a y axis each of length 400, labeled "1 == 20 pixels" and with a notch ever 20 pixels. The axes should cross at (300,300).
5. Make both axes red.

I am lazy and I've been using the same project since the start of Chapter 12.
