$$Dynamically allocated Arrays

Find the errors in the following statements

int$*$ p ;

$*$p $=5$;

Delete p;

int$*$ p $=$ new int;

$*$p $=5$;

p $=$ new int;

int$*$ p $=$ new int$[10]$;

int$*$ p $=5$;

delete p;

int$*$ p $=$ new int$[10]$;

int$*$ q $=$ p;

q$[0]=5$;

delete p;

delete q;

int n $=4$;

int$*$ p $=$ &n;

$*$p $=5$;

delete p;

Assume that the pointer variable p is declared as follows:

int$*$ p;

carry out the following tasks related to dynamic

allocation.

Initialize p with a pointer to

a dynamically allocated

integer.

Set the allocated integer to

$7.$

Return the allocated

memory to the heap.

Set up a dynamically

allocated array of length $5.$

Fill the last element of the

allocated array $8.$

Return the allocated

memory to the heap.

Select all of the following code snippets that are valid

uses of the delete operator.

True False

int n;

int$*$ p $=$ &n;

delete p;

True False

int$*$ p $=$ new int;

delete p;

delete p;

True False

int$*$ p $=$ new int$[10]$;

delete p;

True False

int$*$ p $=$ nullptr;

delete p;

True False

int$*$ p;

$*$p $=5$;

True False

int$*$ p $=$ nullptr;

$*$p $=5$;

True False

int$*$ p $=$ new int$[10]$;

p$[10]=5$;

True False

int$*$ p $=$ new int;

p$[0]=5$;

What do these statement sequences print? If there is a

compiler error, answer $$error$.$

int$*$ p $=$ new int;

$*$p $=3$;

cout $<<*$p $<<$ endl;

delete p;

int$*$ p $=$ new int$[10]$;

for $($int i$=0$; I $<10$; i$++)\{$

p$[$i$]=$ i$*$I;

$\}$

cout $<<*$p $<<<<*($p $+1)$

$<<<<$ p$[2]<<$ endl;

delete$[]$ p;
