Hi, what is the correct way of converting contents of a <string> to
lowercase?
There are no methods of <string> class to do this so I fallback on
strlwr().
But the c_str() method returns a const pointer which cannot be used
with strlwr() as it does the conversion inplace. So, I use the
following logic of copying the contents to a dynamically allocated
char* array and then doing the conversion:

I can't figure how to best display little snippets of shell script using
<pre>. I just got around to organising to bulk validate some of my web

Hello,
I'd like to understand why the following code does not compile. It
looks like a strangeness in connection with overload resolution for the
<complex> header:
The conversion operator double() of class B is called for the member
complex::operator*=(double) as expected, but not for operator*(complex,
double).
The effect is, that the template matching (or overload resolution)

Hi all,
I'm having a problem writing template functions that take
vector<T>::iterator as arguments and I'm sure you guys can set me
straight. Like this:
#include<vector>
using namespace std;
template<typename T>
void test2(typename std::vector<T>::iterator b)

Hi.
Mostly I program in C++, and I'm not fluent in C# and .NET. In my last
project I began to use LinkedList<and suddenly noticed that can't
find a way to sort it. Does it mean I must implement sorting for
LinkedList<myself?
Thanks in advance

You can you program against generic interfaces generically?
For example, how can I make the following code which works for the
non-generic interface also work for the generic counterparts?
public bool Equivalent(ArrayList x, ArrayList y) {
if (x is IComparable) {
x.Sort();
x.Sort();
}

I'm trying to sort a vector<complex<double and can't figure it
out. I recognize the problem is that there isn't a default operator<
for complex data types. I have written my own operator and can use
it, but std::sort doesn't seem to find it. I have copied a very
simple example below. Everything compiles just fine when the line
with std::sort function is commented out, but with that line included
a whole slew of errors are given like:

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,...
