Program to alphabetically merge the three word list files

HW-2

Write a program to alphabetically merge the three word list files
(american0.txt, american1.txt, and american2.txt). The output must
be a file called words.txt and the output must be alphabetically
sorted.

Note that you CAN cheat by using Linux commands to do this. However,
a single C program must implement your process regardless.

"man 3 system" and "man cat" - As Foghorn Leghorn might say "That's a hint son."
