Chain Iterator

Chain Iterator is a C++ class which concats multiple C++ containers to a single iterable object.

Usage

// STL
#include <iostream>
#include <vector>
#include <array>
#include <list>

#include <ChainIterator.h>

int main()
{
    std::vector<int> a{ 1, 2 };
    std::vector<int> b{ 3, 4 };
    std::array<int, 2> c{ 5, 6 };
    std::list<int> d{ 7, 8 };

    auto chainIterator = makeChainIterator(a,b,c,d);

    for(auto& element : chainIterator){
        std::cout << element << std::endl;
    }

    return 0;
}

Output:

1
2
3
4
5
6
7
8
