asked on
locate an entry and related information in the file
Hello,
Does any one have an good idea to implement following question in perl effectively.
suppose there is a file the format is:
metrics range
entry1 0-12
entry2 0-56
entry3 0.2-13.4
....
....
when the program gets an entry name and its value from user(e.g. "entry2 24"),it can locate this entry and its range in the file.Then check if the given value is within range. and report "success" or "fail" to the user.

It's difinitely not.

It's difinitely not. In fact, I already implemented it:
read file one line at one time,then use "split" to parse it and commpare corresponding items with user input.....

thank you very much.
But how about if metric user given is just part of a compound metric in the file.
for example:
metric_name range
--------------------------
m1 1~12
m3+m4 23~34
m7 45~23
.......
what the user input is " (m3 3),(m1 19), (m4 23)..." and the program can make a report indicate the "false" or true" for each metric entry in the file

Sould I post modified question again?
I just now saw your comments... yes, the new question is a different than this one because the compound metrics means you have to save the inputs and loop through the metrics, calculating each one. All the code changes.
I can't take a look at it quite at this moment unfortunately, if the new question is still unanswered later I will answer it, in any event good luck!

(I haven't heard of any classes giving assignments in perl, but the nature of the problem and the way it's phrased is very assignment-like, and I am just making sure).
