		ordu 37 days ago \| parent \| context \| favorite \| on: GCC SC approves inclusion of Algol 68 Front End `int arr[4]; foo(arr);` We can look at this code like it passes an array by reference, but how to pass `arr` by value?

You can pass it by value when putting it into a struct. You can also pass a pointer to the array instead of letting it decay.

void foo(int (*arr)[4]);

int arr[4]; foo(&arr);
