# siv::IndexedIterator
**siv::IndexedIterator** is a header-only indexed iterator library for modern C++.
## Examples
### std::vector
```cpp
std::vector v = { 0, 100, 200, 300, 400, 500 };
for (auto [i, n] : Indexed(v))
{
std::cout << i << ": " << n << "\n";
}
```
```
0: 0
1: 100
2: 200
3: 300
4: 400
5: 500
```
### std::string
```cpp
std::string s = "Hello, world!";
for (auto [i, ch] : Indexed(v))
{
std::cout << i << ": " << ch << "\n";
}
```
```
0: H
1: e
2: l
3: l
4: o
5: ,
6:
7: w
8: o
9: r
10: l
11: d
12: !
```
### std::map
```cpp
std::map m = { { "aaa", "AAA" }, { "bbb", "BBB" }, { "ccc", "CCC" } };
for (auto [i, p] : Indexed(m))
{
std::cout << i << ": " << p.first << ", " << p.second << "\n";
}
```
```
0: aaa, AAA
1: bbb, BBB
2: ccc, CCC
```
