I am a little confused with code I am looking at. My c++ book does not go
into passing a structure to a function so I pulled out a c book which does.
and I do not understand the prototype verses the actual function call. I
will post the code below of the structure, the prototype and and function
call and if someone can explain this I would be very appreciative:
struct data
{
float amount;
string fname;

Guys,
I'm interested in how the compiler implements function calls, can anyone
correct my understanding/point me towards some good articles.
When a function is called, is the stack pointer incremented by the size of
the variables declared in the called function, and then the function will
know where these are in memory relative to the current stack pointer
position. ALso how are variables returned, is that by a set position in the...

I have written the two associated base classes below (Digital_camera and
Review) to manage digital camera and review objects. They are base classes
for which other derived classes can be written to provide more detail.
You'll notice that I've also declared the display functions as "virtual" to
allow for polymorphism. I now need to write a function to display all the
contents of an STL "deque" of pointers to Digital_camera objects. It needs...

The following code introduces a 'generic function pointer' p. When calling
the pointed-to function via this p, one has to typecast p towards a pointer
to the type of the pointed-to function. My question is how to do this if the
pointed-to function is a K&R style declared function, like f. The best I
could come up with is a typecast towards a pointer to a function with
unspecified number and type of parameters (and appropriate return type),...

Hi,
I have just written a simple program to get me started in C that
calculates the number of days since your birthdate.
One thing that confuses me about the program (even though it works) is
how global variables and function returns work...
For example, I have a global array "char datestring;" which is
defined in the function speakdate. speakdate just converts a set of
integers (date variables) to a string.

Hi. I'm more-or-less a C newbie. I thought I had pointers under control until
I started goofing around with this:

/* A function that returns a pointer-of-arrays to the calling function. */
#include <stdio.h>
int *pfunc(void);

Hi all,
I have heard many discussions among my colleagues that main is a user
defined function or not.
arguments in favour:-
1) if it is built in function it must be defined in some header file
but it is n't.

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
