As I know it does not have the same behavior as an array.
Try sizeof on an array and on a pointer. Can somebody explain why false is the wrong answer?

int *p= (int*)malloc(n*sizeof (int));
But the answer is B. Because in arrays it is not possible to change the base address. But we can change here.

Because pointer refers to address of next data similar as an array.

Structure type variables are also block of memory, which is not the same as array. Can anyone explain this?
