$1.$a$)$ After line #$1$ is executed: Which element in the array does $p$ point to$?$

Code segment repeated below for convenience $($click to expand$)$:

void didymus $($int $**q)\{$

$q=q-3$;

$\}$

void ambrosius$()\{$

$//..$

int $**p=$arr$+**arr$;

arr$[2]=(**p)+4$;$\frac{,}{\frac{?}{?}}$#$1$

$p[1]=**arr-1$;$\frac{,}{\frac{?}{?}}$#$2$

$p=(p-2)$;$\frac{,}{\frac{?}{?}}$#$3$

$**(p-1)=(**p)-1\frac{\text{;}}{\frac{?}{?}}$#$4$

didymus $(p+2)$;$\frac{,}{\frac{?}{?}}$ #$5$

The first element $($index $0).$

The second element $($index $1).$
