HI all,
I came across a strange behaviour with read method, and I'm not sure if
this is a filesystem problem or a misuse of this method.
I do the simple following thing :
f = open ('myFile','r')
content = f.read()
f.close()
When I use this lines really intensively sometimes, at random the content

I have tab delimited text file which gets populated on daily basis via
automated process. New entry is written at the bottom. I need to create a
utility which makes a copy of this file with 10 most recent entries.
When I read line using StreamReader object it starts from the top, so
looping though lines and keeping track of the line is not helpful. Is there
anyway to start reading from the bottom or if anyone could suggest some other...

Hello,
I have a question.
I try to print a ascii file in reverse order( bottom-top). Here is the logic.
1. Go to the botton of the file fseek(). move one character back to avoid the EOF.
2. From here read a character, print it, move the file pointer (FILE*) to 2 steps back (using fseek(fp, -2, SEEK_CUR)) to read the previous character.
This seems to be ok if the file has a single line (i.e. no new line character). The above logic...

assumption: I am new to C and old to COBOL
I have been reading a lot (self teaching) but something is not sinking
in with respect to reading a simple file - one record at a time.
Using C, I am trying to read a flatfile. In COBOL, my simple file
layout and READ statement would look like below.
Question: what is the standard, simple coding convention for reading

their corresponding values.
e.g if i have tiDict1 = tiDict1 = {'a':,'b':} i should get

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
