How can you safely pass objects to functions without allowing the function to modify the object?

Pass by constant pointer
Pass by constant reference
Pass by value
Pass by void pointer

The correct answer is: Pass by constant reference

Unlike pointers, references cannot be reassigned to point to a different object. Hence, passing object by reference ensure that the original object does not get modified within the function. On the other hand, passing by value creates a copy of the original object, which can be modified within the function. Passing by constant pointer may also lead to the modification of the object if the function does not use constant syntax. Passing by void pointer does not ensure type safety and therefore should not be used for passing objects to functions.
