=====Game: Farmer and the River=====
Here we are going to implement the classic "Fox, Chicken, Corn" game.

====Rules====
The premise of this game involves a farmer with the above-mentioned items that needs to transport them across a stream in a boat.

The boat, unfortunately, is large enough only for the farmer and one item.

There exists the following relationship with the items:

  * The fox, left alone with the chicken, will eat the chicken.
  * The chicken, left alone with the corn, will eat the corn.

So one needs to craft a careful means of transporting all these items without losing any of them.

====Programming Considerations====

  * Your program should display the current scene (using textual characters, ASCII)
    * visualize the location of the farmer, fox, chicken, corn, river, and boat
  * At the start of the game, prompt the user for a display of the game rules and instructions
  * At the conclusion of the game:
    * display the total number of turns taken before the game reached its end (successful or otherwise) state
    * prompt the user if they would like to play again
  * Create, populate, and use the following functions:
    * **intro();** - a function to display the instructions for the game
    * **display();** - a function to display the current playing field
    * **chkmove();** - a function called after each turn to determine if the game is over (user chooses poorly), or if the game is still in session
  * There are to be **NO** global variables used in your program. Pass any needed variables by value or address between functions
  * Of your variables and functions, you are to pass **at least** one variable by address and manipulate it within the called function (so the changed value is reflected outside the called function as well).
  * Implement your code first in a single .c file- **farmer.c**
  * Once you have a working single-file version of the game, also split it up into multiple files and verify you can still compile/play it. Have at least 4 files:
    * game.h
    * main.c
    * displayops.c
    * process.c
