C++11 does. They are called range-based fors. Remember that you should qualify the type as a reference or a reference to const.

The workaround for C++03 is BOOST_FOR_EACH or boost::bind in combination with std::for_each. More fancy things are possible with Boost.Lambda. Should you be in the mood to frustrate either yourself or your co-workers I recommend the deprecated binders std::bind1st and std::bind2nd.

Here is some example code:

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>
#include <boost/lambda/lambda.hpp>
#include <functional>    

int main()
{
  int i = 0;
  std::vector<int> v;
  std::generate_n(std::back_inserter(v), 10, [&]() {return i++;});

  // range-based for
  // keep it simple
  for(auto a : v)
    std::cout << a << " ";
  std::cout << std::endl;

  // lambda
  // i don't like loops
  std::for_each(v.begin(), v.end(), [](int x) { 
      std::cout << x << " ";
    });
  std::cout << std::endl;

  // hardcore
  // i know my lib
  std::copy(v.begin(), v.end(), std::ostream_iterator<int>(std::cout, " "));
  std::cout << std::endl;


  // boost lambda
  // this is what google came up with
  // using for the placeholder, otherwise this looks weird
  using namespace boost::lambda;
  std::for_each(v.begin(), v.end(), std::cout << _1 << " ");
  std::cout << std::endl;

  // fold
  // i want to be a haskell programmer
  std::accumulate(v.begin(), v.end(), std::ref(std::cout), 
                  [](std::ostream& o, int i) -> std::ostream& { return o << i << " "; });

  return 0;
}

hi Darin, the Enhanced for loop java //... Foreach loop over all elements in arr. for (type var : arr) { body-of-loop } and equivalent for statements java //... For loop using index. for (int i = 0; i < arr.length; i++) { type var = arr[i]; body-of-loop } here's example java double[] ar = {1.2, 3.0, 0.8}; int sum = 0; for (double d : ar) { // d gets successively each value in ar. sum += d; } java double[] ar = {1.2, 3.0, 0.8}; int sum = 0; for (int i = 0; i < ar.length; i++) { // i indexes each element successively. sum += ar[i]; } might that helps

C-style loops can allow for arbitrary increments

This is especially visible when the increment is some non-constant calculation, like when I was trying to implement an optimized prime checker in Kotlin, which doesn’t have C style for loops. As noted in the comments, you can also go back (have a negative increment) using C-style for loops.
