Hello.
If I was to call a method of class T, M for each element in a collection,
I'd do it like this:
vector<int> vec;
....
for_each(vec.begin(), vec.end(), mem_fun_ref(&T::M));
Okay, I can see that mem_fun_REF makes it obvious that I must use a
reference, but why? Is it not possible to pass a function by-reference? As I

Why the following code does not compile? If I change the function

Best regards

We have ptr_fun to handle functions, mem_fun to handle member functions
that will be called through a pointer, and mem_fun_ref to handle member
functions that will be called through a reference.
First, why do we need to have seperate mem_fun/mem_fun_ref? The first
returns a mem_fun_t, and the second a mem_fun_ref_t. But the only
difference between mem_fun_t and mem_fun_ref_t is that they have
different operator() methods. But since...

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,...
