<p><b>New page</b></p><div>==Task 1==<br />
On both the lab machine and the Linux server the pointers for all the types are 4 bytes.<br />
<br />
==Task 2==<br />
lab machine:<br />
&x = 0x22cca4, &y = 0x22cca0, diff = 1 <- (long)(&x-&y)<br />
&x = 0x22cca4, &y = 0x22cca0, diff = 4 <- (long)&x-(long)&y<br />
<br />
Linux server:<br />
&x = 0xffc6e74c, &y = 0xffc6e748, diff = 1 <- (long)(&x-&y)<br />
&x = 0xffc6e74c, &y = 0xffc6e748, diff = 4 <- (long)&x-(long)&y<br />
<br />
The differences are the same, the only differences are the adresses.<br />
<br />
==Task 3==<br />
Lab machine:<br />
&arr=0x22cca0, arr+4=0x22cca4, &arr[4]=0x22cca4<br />
&x = 0x22cca4, &y = 0x22cc9c, diff = 2<br />
&x = 0x22cca4, &y = 0x22cc9c, diff = 8<br />
