$[$Solution copied over for part a$.]$

I will also include the "solution" mentioned in our instructions:

#include

using namespace std;

void comma$($unsigned int$*$ ptr$)\{$

cout ;

cin $>>*$ptr;

$\}$

int main$()\{$

unsigned int tape$[4]=\{0,0,0,0\}$;

unsigned int$*$ ptr $=$ &tape$[0]$;

comma$($ptr$)$; $//,$

$++$ptr; $//>$

comma$($ptr$)$; $//,$

$--$ptr; $//$

while $(*$ptr $!=0)\{//[$

$++$ptr; $//>$

$++(*$ptr$)$; $//+$

$--$ptr; $//$

$--(*$ptr$)$; $//-$

$\}//]$

$++$ptr; $//>$

cout ptr $$ endl; $//.$

return $0$;
