Description

Use copy() to copy elements from a list to a vector.

Demo Code

#include <iostream>
#include <vector>
#include <list>
#include <algorithm>
using namespace std;
template<class T> void show(const char *msg, T cont);
int main()/*from  w  ww .  j ava2 s  .c om*/
{
   list<char> lst;
   // Add elements to lst.
   char str[] = "Algorithms act on containers";
   for(int i = 0; str[i]; i++) lst.push_back(str[i]);
   // Create a vector that initially contains 40 periods.
   vector<char> v(40, '.');
   show("Contents of lst:\n", lst);
   show("Contents of v:\n", v);
   // Copy lst into v.
   copy(lst.begin(), lst.end(), v.begin()+5);
   // Display result.
   show("Contents of v after copy:\n", v);
   return 0;
}
template<class T> void show(const char *msg, T cont) {
   cout << msg;
   T::iterator itr;
   for(itr=cont.begin(); itr != cont.end(); ++itr)
      cout << *itr;
   cout << "\n\n";
}
