Hi all,
I am new to C and I just started to program for a homework.
I included my code down there.
It is a fraction "class". I declared the Fraction struct, tried to
create some invalid fraction, with denominator zero.
A Fraction is created by the newFraction() function, and which in turns
call normalize() function to simplify it, but before, the normalize()
function will do a check, if the denominator is zero, it will give a
error by...

The following function intends to delete "numberoflines" lines from a text
file, named "s" (string pointer) and pointed to by file pointer "fp", starting
from line "line".
Now, the function works an inteded, but I think that this is purely
coincidential.
I'm using a temp file to copy the contents of the text file, and then, copy
the last lines that i want to keep, on top of those i want to delete.I fwrite
an EOF character after the...

I have a class "Call". I have instantiated a Call object in one class then
passed a pointer to that object to another class.
How do I create a *copy* of that Call object using only the pointer?

Hi All
On coding , I think I need some basic help about how to write member
function .
I've readed the FAQ, but I am still confuse about it when coding(reference /
pointer /instance) , so I think I need some "template".
Sorry for my coding experience in c++

HI,
One more small doubt from today's mail.
I have certain function which returns a pointer (sometimes a const
pointer from a const member function).
And certain member function needs reference (or better a const
reference).
for eg,
const PointRange* points = cc.points(ptAligned);

Hello group,
Last week I picked up a thread, which pointed out that if a copy
constructor is created with pointers
instead of reference, there is a danger of it going in infinite
recursion.
My observation:
1. Compiler does not complain.

Hello.
I have written a simple reference-counting smart pointer class template
called RefCountPtr<T>. It works in conjunction with another class,
ReferenceCountable, which is responsible for the actual counting. Here
is the latter's definition:
// --- Begin ReferenceCountable.h ----------
class ReferenceCountable

As long as I write c++ code, I am worry about the
pointer. The more the system is, the dangerous the pointer
is I think.
I must pass pointers erverywhere, and is there a way to
ensure that every object pointered by any pointer will
be deleted and only be deleted once?

Handle Classes
Handle classes, also called Envelope or Cheshire Cat classes, are part of the Bridge design pattern. The objective of the Bridge pattern is to separate the abstraction from the implementation so the two can vary independently.
Handle classes usually contain a pointer to the object implementation. The Handle object is used rather than the implemented object. This leaves the implemented object free to change without affecting...

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....
Now, this would greatly impact the work of software developers. The idea...
