Is there anything equivalent in Julia to do make\_pair on vectors, like in c++?

Example:

```nohighlight
vec[r].insert(std::make_pair(i,j));

```

Best regards

In Julia, you can create a `Pair` with the `=>` syntax, i.e. `i => j` creates a pair whose first element is `i` and whose second element is `j`. You can also just use the `Pair` constructor directly as `Pair(i, j)`, which does exactly the same thing.

Thank you so much for the quick response!  
I would like to be able to insert this structure into an array, is it possible? Like inserting a pair in a vector, as in c++

yeah of course, `push!()`, but remember, it may not be the best approach to direct translate C++ code
