Re: Question about using for_each

I don't seem to be able to use for_each if it should replace a 'for'
loop in a method (constructor in my case) and inside that 'for' loop a
class member variable is being accessed. The presence of this member
variable prevents me from using a static or global method to be passed
as a third parameter to for_each, and mem_fun doesn't seem to work for
me either as I am not going to execute a method of an iterator but
pass an iterator as a parameter. I am not sure that explanation makes
a lot of sense, so below is a sample code. I would like to be able to
replace the 'for' loop inside C class constructor with a for_each.
Please don't pay attention to what is actually happening with these
two vectors of ints, it's just for illustration purposes. Thanks.

#include <iostream>
#include <algorithm>
#include <vector>

using namespace std;

typedef vector<int> vectorInts;
typedef vector<int>::iterator vectorIntsIter;

class C {
  public:

    C(pair<vectorIntsIter, vectorIntsIter> aPair) {
      for (vectorIntsIter iter = aPair.first; iter != aPair.second; +
+iter) {
        // do something that involves member variable
        // which seems to prevent using a static method
        // such as for example this:
        ints.push_back(*iter + 10);
      }
