int calculate(int param) {    vector<int> data{ /*...*/ };    // …    return result;}

The functionality is quite simple: The computer literally manages a stack, on which it always places the variables you define. The compiler keeps track of the positions in the stack where a range was entered—for example, with an opening block brace {. Upon leaving the range with the closing ...
