my dinkumware docu says, vector<...>::rbegin() returns an iterator which
points just BEYOND the end of the controlled sequence.
Is that true?
so I cannot say:
for( riter i=v.rbegin(); i != v.rend(); i++)
{
something = (*i);
}

I have the following code, where good_list is a vector of CUnits:
int high_cutoff = 10;
vector<CUnit>::iterator it;
for (it = good_list.end(); it != good_list.begin(); --it) {
CUnit* ccu = it;
if (ccu->GetCutoff() >= high_cutoff) {
good_list.erase(it);
}
}

Hey again everyone! I have another question for you guys. I am trying to
erase a certain vector element based on what number the user selects.
Here is what I did:
case 'b' :
{
cout << "Please enter note number to clear: ";
cin >> clear_note;
clear_note = clear_note - 1;
vec.erase(clear_note);

Hello, I have a function that adds a std::string to a std::vector. New
entries are added at the front (index 0) of the vector. If the vector
contains a certain amount of elements, the element at the back is removed
when a new one is added. If one tries to add a string already stored in the
vector, that string is supposed to...

I've got a memory overwrite problem, and it looks as if a vector has
been moved, even though I haven't inserted or deleted any elements in
it. Is this possible? In other words, are there any circumstances in
which the STL will move a vector, or invalidate iterators to elements
in the vector, if you don't insert or remove elements?
My actual problem seems to be as follows:
I have class X, which contains an STL vector. The constructor...

Hi all
I want to create a std::vector that goes from 1 to n instead of 0 to n-1.
The only change this will have is in loops and when the vector returns
positions of elements etc. I am calling this uovec at the moment (for
Unit-Offset VECtor). I want the class to respond correctly to all usage of
STL containers and algorithms so that it is a transparent replacement for
std:vector.
The options seems to be:

I want to iterate through a vector and erase elements that meet a
certain criteria. I know there is an algorithmic way of doing this,
but first I would like to know how to do it with normal iteration. I'm
am trying to do something like:
vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);

Hi,
is there any ways that allow us to delete an element in between?
say

Hello
I have a vector<int(aRemovecoll) which is a list of the indexes to
be removed from another vector. The other vecotr contains an object -
I will call it SomeObject. So the other vecotr is a
vector<SomeObject>.
I have created a function like this so far:
UINT uNumElements = aRemoveColl.GetSize();

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...

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,...
