Hi,
I'm new to using std classes, but I was wondering how I could do the
following efficiently with the string class:
Say I had a string with delimited values such as:
"field1,field2,field3,field4"
and I wanted to to place those 4 fields into different variables I would do
something like:
/* Note code quickly pulled from my head - may be wrong :) */

Suppose I have a string, char *str = "1 2 a f g < )"
and I need to check each of the components in the loop using isalpha,
isdigit, isspace. How can I do that?
I tried to do using this code, but gives me a core dump.
char *point;
point = str;
while (point != '\0') {
if (isalpha(point)) // It does not work either: if

Hi,
I am trying to reassign an array of char to a string literal by
calling a function.
In the function I use pointer-to-pointer since I want to reassign the
"string array pointer" to the string literal.
But the second printf seems to give me garbage.
Any advise on what I am doing wrong?
Thanx

Hi, I'm maintaining C# code and am fairly new with C# programming. I'm
looking for codes that's droping the 2nd digit of a nuber printed out and I
suspect it's the code below. Can someone tell me where I can look up
explaination on the String.Format, the format string part like "("{0:.#0}".
What's the trailing 0 and what is that "0:" means? I assume the "#" is the
place holder character for th value obtain after the comma in the code.

Can you do a search for more that one string in another string?
Something like:
someString.IndexOf("something1","something2","something3",0)
or would you have to do something like:
if ((someString.IndexOf("something1",0) >= 0) ||
((someString.IndexOf("something2",0) >= 0) ||

When we assign a managed or unmanaged string literal to a String *, is a new String
created implicitly in the managed heap?
Or in other words, what happens when we assign a string literal to TextBox::Text and then
writing in this TextBox?

hi,
I need user defined function that converts string to float in c.
since the library function atof and strtod occupies large space in
my processor memory I can't use it in my code.

This is such a long posting that I've broken it out into sections.
Note that while developing this patch I discovered a Subtle Bug
in CPython, which I have discussed in its own section below.

THE OVERVIEW
I don't remember where I picked it up, but I remember reading years
ago that the simple, obvious Python approach for string concatenation:

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...
