A struct variable can be passed either by value or by reference depending on the requirements of the function. Passing by value creates a copy of the struct variable whereas passing by reference avoids creating a copy, thus making it more efficient for large struct variables. Passing by const is also possible but it only restricts the modifications to the struct variable inside the function, it doesn't affect how it is passed. Therefore, the best choice is either by value or by reference depending on the specific use case of the function.
