Hi,
I am working on an application, which will run embedded without an OS.
The app is build up out of a couple of well defined parts. At first I
wanted to keep those parts seperated and use opaque data types to
transfer information in between them.
At some stage I was stuck and needed to make a variable global, and I
also needed to make the struct declaration public to some other parts.
Looking through the code I found out that lots...

Hello,
What does Const mean in this c structure ? and what is the delphi equivalent
?
I think const struct just means it can't be modified... is that correct ?
Struct {
Type1 Field1;
Const struct Type2 *Field2;

Hi there,
By chance, I came to learn that it is bad programming practice to
initialize global variables at outside of programs. Is it that bad? In
order to fullfil this, I had to declare them with const, but thereafter
they are no longer variables. Just couldn't see the benefits of this
practice. Any comments or advices are welcome.
Thanks

Hi all,
I did not understand why do the global vars are
initialized to NULL where as the block level variables have random
values? I know that the C standard requires this as was mentioned in a
recent thread.
I want to know why this descrimination is in place. Can't all the
variables be initialised to NULL automatically by the compiler? This
would make programming a little easier.

Whilest I was browesing a tutorial today I came across the infromation
that in standard C variables must be decalred at the beginning of a
block. Meaning:
/****************************************************/
/* ... usual includes and such */
int var = 1;
if(var = 1){
printf("hello world\n");

C++: The Case Against Global Variables
Summary
This article explores the negative ramifications of using global variables. The use of global variables is such a problem that C++ architects have called it polluting the global namespace. This article explores what happens when the global namespace becomes polluted and how to avoid this condition.
The opinions expressed in this article are those of the author alone although many have...

OK, let's say that have a function menu structure declaration
like this (since I basically do):
typedef struct function_item {
char *descrip;
void(*function)(void);
} t_function_item;
typedef struct function_menu {
unsigned short num_items;

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...
