Chapter 16 // Exercise 10 - Principles & Practice Using C++

In this exercise I am using Visual Studio 2017 and modified versions of the graphics files used throughout the chapters. You can find those versions through the link below.

Chapter 16 // Exercise 10

Provide a program where you can choose among a set of functions (e.g., sin() and log(), provide parameters for those functions, and then graph them.

It turns out In_box::get_int() will not correctly return negative numbers. This was because of the check to see if a number had been placed in the box. It checks the first character and if it's not a number it returns -99999 so I changed it to allow the first character to be '-'. Other than that, thanks to the Stored Function we made in the last chapter, this was quite straightforward. 

And the graphics chapters are now over :( Although I am excited to finally start working on algorithms and memory management. I use these concepts a lot at work but I feel like I haven't picked up the basics properly and I had to start running before I could even walk. I've had a look through the rest of the exercises and there are more that use FLTK so it hasn't completely disappeared.
