Hello I took my quiz earlier and I'm kind or curious why I got this question wrong on pointers

Given the following two statements, how might you change the value of a to 4? double a = 3; double *p = &a;    &p = 4;      *p = 4;      p->a = 4; (I selected this one because I assumed that double *p = &a a=4;      ++p;      It is not possible to change a by using p

*p = 4; This mean "change the value pointed to by p".
