Do a git pull and find directory ex03/.

We're supplying a mostly completed .h file (Vector3d.h) that declares some functions and a main() (in file ex03.c) that uses them and verifies their functionality. The .h file is incomplete in a key way, and we don't supply any code implementing the methods it declares. Those things are your job.

You should

• read the code supplied to get a sense of what it's doing and what the required behavior is for your implementation
• complete Vector3d.h by deciding on a type for Vector3d in the typedef statement near the top. Note: make sure you understand how main() is expecting the type to behave before filling in the typedef. This step is, in a way, the hardest part.
• implement the methods declared in vector3d.h according to the specifications it contains and the uses of those methods in ex03.c.
• have no memory leaks. Use valgrind to check. (We will.)

---

Your code must:

• compile without errors or warnings on CSE Linux machines (lab workstations, attu, or CSE home VM) using:

  	gcc -std=c17 -g -Wall *.c
        

• not have changed ex03.c at all
• not have made superfluous changes to vector3d.h
• have no crashes, memory leaks, or memory errors on CSE linux machines
• be pretty, by which we mean clean, compact, tranparent, and robust.

Bonus

We have supplied a solution executable you can use to see expected output.

Turn-In

You should tag your code ex03-final and push to your repository.
