 For example, the C code 

assigned 1 to variable codice_3 by using the dereference operator and a pointer to the variable codice_3.The unary * operator, as defined in C and C++, can be used in compositions in cases of multiple indirection, where multiple acts of dereferencing are required.Pointers can of course reference other pointers, and in such cases, multiple applications of the dereference operator are needed.
