Consider the program below. Trace the code by hand and specify what the output would be if the user enters $12$ and $14,$ respectively, in fun$1()$ when prompted.

#include

using namespace std;

void fun$1($int&$,$ int&$)$;

void fun$2($int&$,$ int&$,$ int&$)$;

void fun$3($int$,$ int, int$)$;

int main$()$

$\{$

int x $=0,$ y $=0,$ z $=0$;

cout $<<$ x $<<\text{'}\text{'}<<$ y $<<\text{'}\text{'}<<$ z $<<$ endl;

fun$1($x$,$ y$)$;

cout $<<$ x $<<\text{'}\text{'}<<$ y $<<\text{'}\text{'}<<$ z $<<$ endl;

fun$2($x$,$ y$,$ z$)$;

cout $<<$ x $<<\text{'}\text{'}<<$ y $<<\text{'}\text{'}<<$ z $<<$ endl;

fun$3($x$,$ y$,$ z$)$;

cout $<<$ x $<<\text{'}\text{'}<<$ y $<<\text{'}\text{'}<<$ z $<<$ endl;

return $0$;

$\}$

void fun$1($int& a$,$ int& b$)$

$\{$

cout $<<$ "Enter two integers? $"$;

cin $>>$ a $>>$ b;

$\}$

void fun$2($int& a$,$ int& b$,$ int& c$)$

$\{$

b$++$;

c$--$;

a $=$ b $+$ c;

$\}$

void fun$3($int a$,$ int b$,$ int c$)$

$\{$

a $=$ b $-$ c;

$\}$
