Can be assigned pointer to pointer

Answer 1

Why don't you just try it? 🤔

int n = 69;
int *pn = &n, *pm = pn;
printf("%d\n", *pm); // 69
int **ppn = pn; // pointer to pointer
printf("%d\n", *ppn); // 69
int ***pppn = ppn; // pointer to pointer to pointer
printf("%d\n", *pppn); // 69

Answer 2

Can be more precise with your question? I don't know what you mean...

Answer 3

can we do this
Int *p;
Int *q;
P=q;

Answer 4

Yes you could do this. For example
int a;
int *p = &a;
int *q;
q = p;
would be correct.
