Are `x = &v` and `*x = v` equivalent?

Question

int * x;
int v = 7;

Given this code, what is the difference between 1. x = &v , and 2. *x = v ? I understand that

Answer 1

x = &v modifies x. After the operation x will point to v.

*x = v modifies the object pointed by x. In the example, x doesn't point at anything because the pointer is uninitialised. As such, the behaviour is undefined.
