What's the output of the following program?

int MyMaxValue$($int& myNumber$1,$ int& myNumber$2)\{$

int temp $=$ myNumber $1+7$;

myNumber $2=$ temp;

myNumber $1=$ myNumber $2+7$

return myNumber$2$;

$\}$

int main$()\{$

int value $1=6$;

int value $2=7$

cout $$ value$2$ value $1$ ;

return $0$ ;
