Why string literals are regarded as char * not as const char *?
(1) void f(char *);
(2) void f(const char *);
f("foo") will call version (1) of function f.
I understand that the exact type of literal "foo" is char, which by means
of standard conversion becomes char *. Still, there's something going wrong
here, because this allows modification of "foo", which in my opinion should

Does anyone know if a easier way (built in function, or something) that
can verify that a string is an alphanumeric number? Here is what I am
doing now:
for(i=0; i < strlen(temp); i++){
if(!isalnum(temp)){
return 1
}

Hello!
I've programmed in c a bit, but nothing very complicated. I've just
come back to it after a long sojourn in the lands of functional
programming and am completely stumped on a very simple function I'm
trying to write. I'm writing a function that takes a string, and
returns an array of strings which are the result of splitting the input
on whitespace and parentheses (but the parentheses should also be
included in the array as...

Hello List,
I have ar more or less academical question.
Can there arise runtime errors in a program, if the include of
<string.h> has been forgotten? If all the arguments to the functions of
<string.h> are correct, is it possible that an error occurs, and what
an error might this be?
Regards

I have a question about string literals with C++/CLI.
Is there a difference between the following two lines?
String ^s1 = gcnew String("Hello");
String ^s2 = gcnew String(L"Hello");
I have been playing around with the compiler options for "Character Set" and
"Common Language Runtime Support" and those two lines compile fine. I am
thinking that when compiling with /clr, "Hello" is a string of Unicode

I am working with a C API which often requires a char* or char buffer. If a
C function returns a char* I can't use string? Or can I? I realise I can
pass a char* using c_str() but what about receiving a char buffer into a
string?
Reason I ask is otherwise I have to guess at what size buffer to create?
And then copy buffer to a string. Doesn't seem ideal.

Hi guys,
I am a newby in the C/C++ world, and I am beginning to work on a
rather simple TCP/IP proxy application which must be able to handle
large volume of data as quickly as possible.
Since this application has to process and distribute plain text around
the network, I am wondering if there are any peformance differences
between C++ std::string and C char in run time?

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....
