Traverse a List Using an Iterator?

Question

I need sample for traversing a list using C++.

Answer 1

The sample for your problem is as follows

  #include <iostream>   #include <list>   using namespace std;    typedef list<int> IntegerList;   int main()   {       IntegerList    intList;       for (int i = 1; i <= 10; ++i)          intList.push_back(i * 2);       for (IntegerList::const_iterator ci = intList.begin(); ci != intList.end(); ++ci)          cout << *ci << " ";       return 0;   } 

Answer 2

To reflect new additions in C++ and extend somewhat outdated solution by @karthik, starting from C++11 it can be done shorter with auto specifier:

#include <iostream> #include <list> using namespace std;  typedef list<int> IntegerList;  int main() {   IntegerList intList;   for (int i=1; i<=10; ++i)    intList.push_back(i * 2);   for (auto ci = intList.begin(); ci != intList.end(); ++ci)    cout << *ci << " "; } 

or even easier using range-based for loops:

#include <iostream> #include <list> using namespace std;  typedef list<int> IntegerList;  int main() {     IntegerList intList;     for (int i=1; i<=10; ++i)         intList.push_back(i * 2);     for (int i : intList)         cout << i << " "; }
