Thread: Homework Help

Your report format was not set up with code tags around it (that's the # icon in the advanced forum editor), so it was torn to smithereens and is useless.

For this assignment:
Post up YOUR code, or pseudo code, and just tell us what YOU are stuck on, and USE CODE TAGS! Requests without code tags around the code or formatted text, is routinely ignored, because it can't be grok'ed.

Your assignment is your assignment, we can't help you with how much work you were given.

We do know a thing or two about those math equations, however.

Glad you're getting over the flu.

1. To understand. Connotes intimate and exhaustive knowledge. When you claim to ‘grok’ some knowledge or technique, you are asserting that you have not merely learned it in a detached instrumental way but that it has become part of you, part of your identity. For example, to say that you “know” LISP is simply to assert that you can code in it if necessary — but to say you “grok” LISP is to claim that you have deeply entered the world-view and spirit of the language, with the implication that it has transformed your view of programming. Contrast zen, which is similar supernal understanding experienced as a single brief flash. See also glark.

2. Used of programs, may connote merely sufficient understanding. “Almost all C compilers grok the void type these days.”

I'm not fond of the term either, but the jargon file is there for the rest of us.

Thanks Whiteflags... I'd never heard the term before.

Also I was wondering if you could check out my logic for this program it is an ISBN reader the requirements are in the attached word file and here is my logic :

Prototype check digit function

Define ISBN as 15
Also indicate Array name index [ISBN]
Use a while loop in order for the code to be run again with tolower(runagain==y)
Prompt user to enter isbn#
Read character string into array using scanf(%s, index)
Using while loop validate user enter digits using isdigit()
Using nested for loop convert elements of index[ISBN] using alphanumeric to integer using atoi()
Then pass converted index[ISBN] to function check_digit(index[])

Now here is my question how can I make check_digit do what I need it to do without naming each element of the array int a int b etc… and going (a*1)+( b*2)+( c*3). Because the algorithm I found is not working out . I know I need to use modulus 11 %11 I think. Also if you could look at this logic and tell me any problems you see I would appreciate it. I mean I guess I could ask them to enter isbn store each of the using scanf as int a int b int c and never use a function call but if they entered a negative number itr would be an issue.

Alright here is my logic I do not think I am right but This is my first attempt at the logic also the instructions are in attached word file sorry it is in such huge font

Logic:
state variables store num. bagel price etc...

declare file point to bagel.seq

use an if statement and fopen to open the bagel.seq
use printf to state if file does not open
use else command if file does open
use printf with formatted conversion identifiers and put store number bagel name bagel price etc.
use fscanf to print out the information from the bagel.seq file in sequential order under the formatted columns
use while loop to keep it reading information from the bagel. seq file until end of file
use fclose to close the file.

The only thing I am not sure how to do is the math

And with the ISBN program I was showing my logic...so you could point me in the right direction or look at where I might have errors.. my professor has told me that I have to work out the logic before I start on the code, so That is what I was trying to do

Can you do the file reading yet?

Then I have to create a report named bagel. rpt that is suppose to look like a formated table like the one below I just am unsure of how to make the table.

We have a faq on formatted output you can read.

and calculate the precentages.

Percents

Obviously not tater, but I have to admire your ability to understand so much completely, and, make it a huge part of your life.

I know how to read from the bagel.seq file but I am confused on how to make it write to the bagel.rpt file and then display the information in the form of a report. My teacher said to use fprintf in place of the printf in my logic but that does not make any since to me since that is so early in the program I thought I would need to use the fprintf sometime after I used the fscanf

now would I use the fputc command in a while loop to copy the text from the bagel.seq file into the bagel. rpt These are the hints that she gave use, but am not sure which command is more appropriate. and does the fput need to be the fputc or just plain fput. also when I create the . rpt do I create that as a text file in notepad and then have the .seq written into the .rpt file.
·fgets and/or fscanf may be useful in reading the file, and fput and/or fprintf may be useful for printing the formatted report.
·An array for keeping track of Store Totals may, also, be useful.
