Which of the following code $($i$)$ represents the correct implementation of the DISPLAYCLASS function?

#include

#include $//...($i$)...$ missing code for the function.

int main$()$

$\{$

std::stack stackClass;

stackClass.push$("$John$")$;

return $0$;

$\}$

a$.$ void displayClass$($std::stack myStack$)$

$\{$

while $(!$myStack.empty$())$

$\{$

b$.$ void displayClass$($std::stack myStack$)$

$\{$

while $(!$myStack.empty$())$
