0.a Presume the following code has run

int x =4;

int* y = &x;

int** z = &y;

int a = 10;

Write 4 different assignment operations that set x equal to the value of a;

0.b Presume the following code has run

int x =4;

int* const y = &x;

int** const z = &y;

int a = 10;

Which of your assignments (if any) from 0.a are now invalid?

What does the const modifier do to each of the pointers its applied to?
