Programming Tips

							                         Programming Tips
   If you declare an array as a global variable then there is no reason to pass it
    to a function.
   Printing the array and message might best be done in the same function
    (assignment 1).
   Might be best to simplify the code by writing one function to move and one
    function to check if blocked (assignment 1).
   Make it obvious where a function begins:
         /*********************************************
         * function description ….
         * function description ….
         ********************************************/
   You should not have any warning messages after a compile (build). For
    example, if you leave out #include <stdio.h> and use the printf function you
    would get a warning message.
   If you write a function that returns a value then you better be using the value
    returned. Why else would you be returning the value.
   Never pass a #define variable to a function. They are automatically available
    to all functions within the same file.
   Get help from anyone or myself if you get stuck. I’ll ‘guide’ you through the
    program but you still need to do it.
   One-word descriptions for a function like ‘Down’ does NOT describe the
    function well.
   After a program is working fine, and thoroughly tested, go back and fine-tune
    it for structure, comments, etc..
   Divide and conquer: build and test each function as you go before building the
    next function.
   It is more efficient, if a variable can have only one of 2 values, to code it as:
         if variable == 1                                     if variable == 1
             ……..                       instead of                ……..
         else
             ……..                                             if variable = 2
                                                                  ………
   Program should have main function first followed by all other functions listed
    in order called.
   I do not need your sample output.
   Avoid functions that simply call another function.
   Keep main function simple.
   Remove testing statements before turning in assignment.
   Use standard library functions instead of writing your own.
   printarray(); //Prints the array           this is a redundant comment
   No one statement functions.
   Place prototypes at beginning of program and outside of main.
   Avoid too may spaces and comments
