Consider a programming language with pointer types and an explicit dereferencing operator. The programmer deallocates memory and there is no safety mechanism implemented to detect the emer- gence of dangling references. Suppose that assigning to a pointer the value null does not free the memory it pointed to, it merely sets the pointer value to null, ie the pointer now does point anywhere. free frees the memory (without clearing it), but the pointer still points to the old place. (i) What does the following program print? Explain int *p, *q P new int ; *p = 5; q=p: P null ; write (q)
