Does anyone know of the fastest way to convert a CString of numbers ie
"00000001" to the binary representation in an int?
for example
CString myVal = "00000001";
int myIntVal = 0;
myIntVal = CStringToBinary(myVal);

Hi,
I learned C++ recently and I made a string class.
A code example is this:
class CString
{
public:
inline CString(const char *rhs)
{
m_size = strlen(rhs);

hi,all
I use a c++ (build in vc6) dll in c#, do I need to care about the calling
convention? Cause it always gives me a unexpected calling!
I used it in c# like this:
public static extern string GetMC(string strID1, string strID2);
private void button6_Click(object sender, System.EventArgs e)

Dear All,
I saw some people using
#include <string.h>
some people using
#include <cstring>
What is the difference between the two? I can find the file string.h at
/usr/include. I don't know if cstring is a file and if so, where to find it.

Hi all,
Not sure if this is OT?
I have a function in a library written in C++ which returns a
strdup(s.c_str()) to an application written i C. Running Valgrind on my
C-application shows this results in memory leaks due to the c_str is never
freed.
Example:

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...
