I was asked this question in an interview.
The points I answered are like this
1) an index pointing to the current position;
2) resize if neccessary.
Can anybody elaborate more?

I want to learn C++ by using Vim and MinGW as compiler. I'm interesting at "C++ Primer (4th Edition)" and "C++ Primer Plus (5th Edition)" but I don't know how about it different. It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

In unmanaged c++ dll i have a function which takes constant std::string as argument
Prototype : void read ( const std::string &imageSpec_ )
I call this function from managed c++ dll by passing a std::string.
When i debug the unmanaged c++ code the parameter imageSpec_ shows the value correctly…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

Hi,
I have this destructor that create error at runtime "vector iterator not dereferencable".
The gridMatrix is a std::vector<std::vector<std::vector<AtomsCell< Atom<T> * > * > * > * >
I added the typename and also the typedef but I still have the error.
I will move…

I have this implementation of vector that I've been working on for a few days using examples from a textbook:
#include <iostream>
#include <string>
#include <cassert>
#include <algorithm>
#include <cstring>
// Vector.h
using namespace std;
template <class T>
class…

I want to create a vector<vector<int>> where the outer vector is fixed (always containing the same vectors), but the inner vectors can be changed. For example:
int n = 2; //decided at runtime
assert(n>0);
vector<vector<int>> outer(n); //outer vector contains n empty vectors
outer…

That's x \ y using mathematical notation. Suppose
x <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,2,1,1,1,3)
y <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1)
How can I get a vector with ALL the values in x that are not in y. i.e the result should be:
2,1,1,3
There is a similar question here…

Assuming I have 2 STL vectors:
vector<int> a;
vector<int> b;
Let's also say the both have around 30 elements.
How do I add the vector b to the end of vector a?
The dirty way would be iterating through b and adding each element via push_back, though I wouldn't like to do that!
