Homework & Coursework Questions

What's the business about "Without school/professor/course information, you will be banned if you post here!"?

edit by bakunin: and what does your posting have to do with this thread?

The forum has agreed with education world in order to not keep on tracking posts ( though we do depending the type of request...) and refuse anything not from professionals to create a dedicated forum for schools/homework but it has strict conditions for both sides: The student agrees what he post here is seen by all AND can not remove once happy and has to comply to the rules by filling the template that has been accepted by education authorities... For the people helping, you are now NOT to answer the question/topic... but to help, guide or correct the student that has to do the work himself...

I am not sure what the problem is I have followed the templet provided. If examples of code connot be given to help solve a problem then all I need is a book not the expertise of the Forum. I have tried all the suggestion given after exhausting the information recieved in class. I do believe the problem is not with the code but with the sequence it is written in.

So what we have established is that what needs to be matched is 5 digits (not numbers) in a row and that to the left (from the beginning) and to the right (right until the end) of them there can be zero or more characters that are NOT numbers. The negative complement of a range or class of characters inside square brackets is done with the negation operator ^ as the first character inside those brackets.

What we will do in this section is give hints and try to help you on your way to understanding, not provide complete answers. The reason for this is two-fold:There is nothing easier for us than to just provide the answer, but then we really would not be helping you.

Retried your suggestion a second time it worked found that I fat fingered the command the first time

What about a line like this:

Code:

this line has five 12345 numbers and 1 extra number

Thanks for all the input. I reread all the threads and went back over what I had done and found that I had fat fingered one of the earlier commands that were suggested. The -w option made everything come together not only for that lab exercise but for two other exercises in that same lab.
