Part $2$: Pointers $(30$ marks$)$

Create a program and set up the variables as shown in the diagram. Complete the following steps for the program:

Part $2$A:

$1.$ Create a function 'setter' with parameters P and a new value k $($integer$).$ The function should follow the pointer and change the integer at the end of the chain to the new value. $[8$ marks$]$

$2.$ Call 'setter' in main with $\backslash (\backslash$mathrm$\{$k$\}=2\backslash ).$ When it returns, demonstrate that the new value of i was changed $($hint: print $\backslash ($ i $\backslash )).[2$ marks$]$

$3.$ Create a swap function with parameters A$2$ and B$2.$ The function should swap them such that A$2$ now points at B and B$2$ now points to A$.$ Call this function with A$2/$B$2$ in main. $[8$ marks$]$

$4.$ Call 'setter' with $\backslash (\backslash$mathrm$\{$k$\}=8\backslash ).$

$5.$ Now print all variables $($dereferenced to i or j $)$ in the following format: $[2$ marks$]$

Part $2$ B: Finally, draw the new diagram for the new variable setup. $[10$ marks$]$
