To create a program that can perform the task of a binary counter, in incrementing or decrementing fashion.

In “The C Book”, please read through Chapter 5.

It is your task to write a program that, upon accepting various pieces of input from the user, acts as a binary counter, displaying the resultant values in binary as from a starting to and ending progression.

Your program should:

• have valid, descriptive variable names of length no shorter than 4 symbols
• have consistent, well-defined indentation (no less than 4 spaces per level of indentation)
  • all code within the same scope aligned to its indentation level
• have proximal comments explaining your rationale and what is going on, throughout your code
• to STDERR, prompt for the starting value (0-1023)
  • properly store this in a variable of type signed short int
• to STDERR, prompt for the ending value (0-1023)
  • properly store this in a variable of type signed short int
• immediately after each input, check to make sure starting and ending values fall appropriately in the range stated; if in violation, display an error (to STDERR) and exit with a non-zero value.
• check the starting and ending values to determine if we are to perform an incrementation or a decrementation.
• in binary, display the starting number and all the others as well to STDOUT
• proceed to the next value in sequence, doing the same
• keep going until you have arrived at the ending value, displaying it as well
• using a single return statement at the conclusion of the code, return a 0 indicating successful operation

Some additional points of consideration:

• Note that the driving variables in your loops need to be at least of type short int, otherwise you may get a warning when you compile it.

lab46:~/src/c4eng/bcf0$ ./bcf0
Enter starting value (0-1023): 12
Enter ending value (0-1023): 28
0000001100
0000001101
0000001110

The execution of the program is short and simple- obtain the input, do the processing, produce the output, and then terminate.

Enter starting value (0-1023): 17
Enter ending value (0-1023): 0

In the C4ENG public directory, inside the bcf0 subdirectory, will be a copy of my implementation (in executable form), which abides by the project specifications. Please compare its output against that of your implementation.

To successfully complete this project, the following criteria must be met:

• Code must compile cleanly (no warnings or errors)
• Output must be correct, and match the form given in the sample output above.
• Code must be nicely and consistently indented
• Code must be well commented
• Do NOT double space your code. Group like statements together.
• Output Formatting (including spacing) of program must conform to the provided output (see above).
• Track/version the source code in a repository
• Submit a copy of your source code to me using the submit tool.

To submit this program to me using the submit tool, run the following command at your lab46 prompt:

$ submit c4eng bcf0 bcf0.c
Submitting c4eng project "bcf0":
    -> bcf0.c(OK)

SUCCESSFULLY SUBMITTED

You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches.

What I'll be looking for:

78:bcf0:final tally of results (78/78)
*:bcf0:proper error checking and status reporting performed [13/13]
*:bcf0:correct variable types and name lengths used [13/13]
*:bcf0:proper output formatting per specifications [13/13]
*:bcf0:runtime tests of submitted program succeed [13/13]
*:bcf0:no negative compiler messages for program [13/13]
*:bcf0:code is pushed to lab46 repository [13/13]
