"for(auto x : counted(v)) { ... x.value ... x.index ... }" |
|
||||
x.value is a reference to the element in the container (so you can change it's value), x.index is what it is. |
|
||||
Container should have forward iterators. |
|
||||
|
|
||||
|
|
||||
This headers is purely a handy tool for the range-based-for-loops (ie "for(auto x : counter(v))"). Using it explicitly with iterators is not recommended! |
|
||||
|
|
||||
|
|
||||
There is no const version of it. Doing "for(const auto x : counted(v))" doesn't make it impossible to change x (so the element in the container can be modified). |
|
||||
|
|
||||
|
|
||||
Example: |
|
||||
for(auto x : counted(v)) { |
|
||||
std::cout << "v[" << x.index << "] = " << x.value << std::endl; |
|
||||
x.value *= 2; |
|
||||
} |
|
||||
|
|
||||
This will output the container v, with it's indeces. And it will multiply every value in v by 2. |
