1. C programming (20 Points):

   These two files need a main() to run their functions countWithList() and countWithTree(). Then all three C files need a header file to inform them of what the others have that they need. Please finish both the main() and header.h.

   Please note! Not everything needs to be shared.

   • main() needs countWithList() and countWithTree()
   • Both countWithList() and countWithTree() need getNextNumber().
   Otherwise, it is best not to share too much, kind of like keeping methods and members private in C++ and Java.

   header.h

   Sample Initial Output:
