Solution
The true statement regarding generic (void) pointers is: "Void pointers cannot be dereferenced without explicit casting."
Here's why:
-
Void pointers cannot be dereferenced directly: This is because the compiler doesn't know the data type of the object pointed to by the void pointer, so it wouldn't know how many bytes to read.
-
Void pointers cannot be dereferenced: This statement is partially true. Void pointers cannot be dereferenced directly, but they can be dereferenced after being cast to another pointer type.
-
Void pointers can only be dereferenced with explicit casting: This is the correct statement. Before a void pointer can be dereferenced, it must be cast to another pointer type.
-
Void pointers behave the same as other pointers in dereferencing: This is not true. Other pointers can be dereferenced directly, but void pointers cannot.
