elevatorSimulator

This program provides an example of an elevator simulator. It was created for educational purposes (specifically CSE3310).

Think of this system as 3 parts:

1. The elevator GUI, which provides a way to provide stimulus (events) to the system. It is coded in the C++ language. A majority was created using the fltk gui layout program known as 'fluid'.
2. The elevator, which simulates the physical elevator. This is coded in the C programming language.
3. The elevator controller, which controls the physical elevator based upon the inputs recieved. It is coded in the C language.

to change the UI:

cd ./src
fluid elevatorGUI.fl

to compile the source code

make clean
make

to execute the program

./eSim

Requirements: (Note, these requirements do not cover the Elevator Controller, only the elevator simulator)
