Unusual control structure

[peter nn]

Does C++ have something like

for (i = {1, 2, 3, 17, 39, 151, etc})
{
	printf("%d\n", i);
}

For same cases (complex code) using arrays in "for" and "while" loops is very inpractical.

array = {1, 2, 3, 17, 39, 151, etc};
for (i = 0; i < array.size; i++)
{
	printf("%d\n", array[i]);
}

Best regards,
Peter

I think C++0x will introduce something similar

Anything new before giving up :)?

Nope. This is the closest:

std::vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(17);
v.push_back(39);
v.push_back(151);
for (size_t a=0;a<v.size();a++)
    std::cout <<v[a]<<std::endl;

#include <boost/array.hpp>
#include <iostream>

typedef boost::array<int,6> Array;
Array a = { 1, 2, 3, 17, 39, 151 };
for( Array::const_iterator i = a.begin(); i != a.end(); ++i )
    std::cout << *a << std::endl;

or better yet

#include <algorithm>
#include <boost/array.hpp>
#include <boost/lambda.hpp>
#include <iostream>

boost::array<int,6> a = { 1, 2, 3, 17, 39, 151 };
std::for_each( a.begin(), a.end(),
    std::cout << boost::lambda::_1 << '\n' );
