I'm trying to add citations to this latex formatted paper. I know the bibtex file is causing the issue. I will try to use this document as a reference once I have a working version. If anyone has an...

I've changed quite a bit of the code to something I understand. Also, I apologize about the forum homework policy. The question posted previously was just asking about some crazy C syntax that I did...

1. The problem statement, all variables and given/known data:
Create a lex specification file that reads a C source program...

Thanks for the reply! I don't clearly understand the code you've provided me. In fact I'm a bit confused :confused:. Is there any other way to append the line numbers other than what I think I'm...

Alright, so I'm writing a file for the lexical analyzer (lex). It will be used to check C code (collecting the identifiers and storing those names along with the line numbers the identifier was found...

Oh yeah totally forgot about the defined() function. Thanks Corona!

I'm filling in a table of values for grades. I decided to go with reading into a hash from the files but I'm coming up with an error when printing a value that does not exist. I need to know if I can...

Thanks for the reply. I fixed the issue earlier. The post must have been concatenated to my earlier post with the code I used.;)

Sorry about that. The only little tweak I have now is that the hash is picking up the blank lines from input. I don't want the blank line. That's the reason I posted the " : 2 times, lines 1, 5," in...

Thanks for the reply. I tried the expression's you've provided and it still has problems. I believe it's just the blank line in general when doing output. Your response is good enough for a thanks. :)

Hello!
I'm trying to tweak my regular expression to take care of this tedious little "blank space" problem. I don't know what's causing the " : 2 times, lines 1, 5," to be printed.

Here is...

Thanks for the reply. I made some progress with creating another hash and using the value from the %occurCount hash as the key to the new %lineConcat hash. However, my output is still interesting....

This program takes much of my previous assignment but adds the functionality of printing the concatenated line...

Thanks!

Works perfectly!
Thanks rdrtx1.

Hello. I've been thinking about how to go about this. I know I'm close but still does not work. I need to remove any word in that is not at least 2 characters long. I've removed all the...

I ended up using the substr() function. Thanks for the help. I will check that out later.

Thanks for the comment.
When I tried this below (or I may not have done it right):
if ($ARGV[0] eq "m/^-(\d+)$/")
{
print "I think it works\n";
}
It gives a compile error of unrecognized...

Hello.
I'm new to Perl and I am not sure how to interpret command line arguments in the program. I am writing a program similar to the Unix utility 'tail' and need to check if first argument is '-1'...

Thanks everybody for the help! I checked out 'ed' and learned some new tools to use. I ended up attacking the problem from a different point of view (more creative but it works the way I need it to)....

I'm using sed to switch integers (one or more digits) to the other side of the ':' colon. For example: "47593:23421" would then be "23421:47593". The way it functions right now, it is messing my...
