Return an array in c++

Question

Suppose I have an array

int arr[] = {...};
arr = function(arr);

I have the function as

 int& function(int arr[])
 {
//         


        

Answer 1

You're returning a reference to an int, not a reference to an array.

You want :

(int*)& function(int arr[])
{
     /// rest of the code
     return arr;
}

That said, as others already said, that's not good practice.
