A simple implementation like Python's zip

zip.cpp

#include <list>
#include <utility>
#include <iostream>

using namespace std;

template<class T1, class T2>
list< pair<T1,T2> > zip(const list<T1>& container1, const list<T2>& container2)
{
	list< pair<T1,T2> > result;
	typename list<T1>::const_iterator it1;
	typename list<T2>::const_iterator it2;
	for(it1=container1.begin(), it2=container2.begin(); it1!=container1.end() && it2!=container2.end(); it1++, it2++)
		result.push_back(make_pair(*it1, *it2));
	return result;
}

int main(int argc, const char *argv[])
{
	int a[] = {1,2,3,4,5,6,7};
	double b[] = {9.0,8.0,7.0,6.0,5.0,4.0,3.0,2.0,1.0};
	list<int> c1(a, a+7);
	list<double> c2(b,b+9);

	list< pair<int,double> > result = zip(c1,c2);

	list< pair<int,double> >::const_iterator iter;
	for(iter=result.begin(); iter!=result.end(); iter++)
		cout << "[" << iter->first << ", " << iter->second << "]" << endl;
	return 0;
}
