Solution: Tuplezip Algorithm

Solution: Tuplezip Algorithm

Learn about the process used to solve the tuplezip algorithm challenge.

The tuplezip function for the std::tuple container

Let’s execute the provided solution for the tuplezip challenge and observe the code output. Subsequently, we’ll dissect the code step by step.

Press + to interact
#include <tuple>
#include <vector>
#include <iostream>
template <typename InputIt1, typename InputIt2, typename OutputIt>
OutputIt tuplezip(InputIt1 first1, InputIt1 last1,
InputIt2 first2, InputIt2 last2, OutputIt dest)
{
auto it1 = first1;
auto it2 = first2;
while (it1 != last1 && it2 != last2)
{
*dest++ = std::make_tuple(*it1, *it2);
*it1++;
*it2++;
}
return dest;
}
int main(){
std::vector<int> range1 = {1, 2, 3, 4};
std::vector<int> range2 = {5, 6, 7};
std::vector<std::tuple<int, int>> result(range1.size() < range2.size() ? range1.size() : range2.size());
auto result_end = tuplezip(range1.begin(), range1.end(), range2.begin(), range2.end(), result.begin());
std::cout << "{ ";
for (auto e : result)
std::cout << "(" << std::get<0>(e) << "," << std::get<1>(e) << ") ";
std::cout << "}" << std::endl;
}
