Task 1

On both the lab machine and the Linux server the pointers for all the types are 4 bytes.

Task 2

lab machine:

&x = 0x22cca4, &y = 0x22cca0, diff = 1      <-   (long)(&x-&y)
&x = 0x22cca4, &y = 0x22cca0, diff = 4      <-   (long)&x-(long)&y

Linux server:

&x = 0xffc6e74c, &y = 0xffc6e748, diff = 1    <-   (long)(&x-&y)
&x = 0xffc6e74c, &y = 0xffc6e748, diff = 4      <-   (long)&x-(long)&y

The differences are the same, the only differences are the adresses.

Task 3

Lab machine:

&arr=0x22cca0, arr+4=0x22cca4, &arr[4]=0x22cca4
&x = 0x22cca4, &y = 0x22cc9c, diff = 2
&x = 0x22cca4, &y = 0x22cc9c, diff = 8
