Hi,
I'm having problems storing large amounts of objects in a ZODB.
After committing changes to the database, elements are not cleared from
memory. Since the number of objects I'd like to store in the ZODB is too
large to fit in RAM, my program gets killed with signal 11 or signal 9...

I need help on a problem, as described below. I am reading a file
"input.txt"which has data like this:
abc def gh izk lmnopq rst uvwxyz
I am using fstream object to read the file and writing into a dynamic
array. My problem is that the array shows extra z and probably because
of this further processing gives run time error in borland compiler.
Can you please tell me, if the problem is related to handling end-of
line , how do i do...

Hi Guys,
(see actual code below)
I wrote a little program that is supposed to read a file (input.txt)
into memory (using a stack) and then reverse the file and display it to
output. It works, but I still get some errors when i try to compile
it:

I have gotten the program to compile with gcc on WinXP.
If the file i read doesnt have alot of records, it runs thru. But once
i add more, it dies. In this program i have 4 files setup to read. The

Hello,
I've encountered a strange problem which I can't seem to explain.
I've written a simple C++ class that deals with a certian binary file.
In one of the methods there, I wish to update a file - namely to read
a certain field whose offset I know, and then write to another field,
whose offset I also know.
In order to read the data, I first use file.seekg(offset, ios::beg),
and then a read command; I've checked the variable, and...

I am trying to compile as much code in 64 bit mode as
possible to test the 64 bit version of lcc-win.
The problem appears now that size_t is now 64 bits.
Fine. It has to be since there are objects that are more than 4GB

The problem is, when you have in thousands of places

hey, i'm trying to write a simple program to read gif87a non-
interlaced format with a single image-descriptor ---
I am using djgpp on windows xp.
Sounds simple enough, unfortunatly data in the format is arranged
primarily in single-byte unsigned integers.
So i've been reading them in a chars and casting them as unsigned
chars into an int.

Hi, I am writing a binary file with matlab that consists of a couple
hundred double values and then reading it in with c++. The problem
arises in c++ when I try and read in the files. At a specific point it
stops and wont read any more values. I use this code to open it and
read it:

After about twenty simmilar reads it fails, returns an...

I am using WriteXML/ReadXml pair to save DataSet for later use. DataSet
is built by reading textfiles and storing their data to different
DataTables. Each file contains several complex values, that are

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
