How to do it...

We will transform a vector's content by removing items in different ways:

1. Let's import all the needed headers and declare that we use the std namespace:

       #include <iostream>       #include <vector>       #include <algorithm>       #include <iterator>             using namespace std;

2. A short print helper function will print our vector:

       void print(const vector<int> &v)       {           copy(begin(v), end(v), ostream_iterator<int>{cout, ", "});           cout << '\n';       }

3. We'll begin with an example vector containing some simple integer values. We'll also print it, so we can see how it changes with the function we apply to it later:

       int main()       {           vector<int> v {1, 2, 3, 4, 5, 6};           print(v);

4. Now let's remove all the items with the value 2 from the vector. std::remove ...
