Gurus,
I have the following implementation of a member function:
class A
{
// ...
virtual double func(double v);
void caller(int i, int j, double (* callee)(double));
void foo() {caller(1, 2, func);

Does the following program exhibit undefined behavior? Specifically,
does passing a struct by value cause undefined behavior if that struct
has as a member a pointer that has been passed to free()?
#include <stdlib.h>
struct stype
{
int *foo;
};

Hi,
I'm a C programmer taking my first steps into the world of C++.
I'm currently developing a C++ 3D graphics application using GLUT
(OpenGL Utility Toolkit written in C) for the GUI components.
The application is built around a "World" object that contains a "GUI"
object that is a C++ wrapper around GLUT. What I'd like to do is pass a
pointer to a member function in the World class to function in the GUI

Hi,
I'm a bit rusty with the wonderful language of c++. I worked with it,
maybe 6 or 7 years ago and now I need to knock the dust off. But I was
perusing some code when I noticed that this one programmer put the
entire class in the header file. I'm not sure what the point to that

this?
And if you do want to, what are the pro's and cons of doing it. Are

I am a c++ newbie, so please excuse the ignorance of this question.
I am interested in a way of having a class call a general member
function of another class.
Specifically, I am trying to write an ordinary differential equation
class that would solve a general equation in the form:
dx/dt = f(x,t).
The ode class shouldn't know anything about f, except how to call it.

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...
