Question $5$

We saw in class that there are several methods$/$notations to refer to an element of an array. In exam $2($topic: arrays$),$ A$[$i$]$ was used to access a particular celli

of array $A.$

The code below uses a for loop to access the content of an array of doubles and print its content, element by element.

double $A[5]=\{4\mathrm{.}1,4\mathrm{.}2,4\mathrm{.}2,4\mathrm{.}4,4\mathrm{.}5\}$

int $i$;

for $)=0$;$i<mi>(</mi><mn>5</mn>$;$i++$

cout $A[i]{}^{\text{'}}{n}^{\text{'}}$;

If your program already has a pointer pd that is defined and is pointing to the beginning of array $A,$ check below all the equivalent expressions that can be

used instead of $A[i]$ in the code above. $($There may be more than one answer!!!$)$

pd$[$i$]$

$*($pd$+$i$)$

$*($A$+$i$)$

$*$A

&A$[$i$]$

$(*$pd$+$i$)$

&pd$[$i$]$

$*$pd$,$ also including the following command in the loop after the cout statement: pd$++$;
