Consider the following program written in $C++$ syntax, what are the values of the list array after the call to fun function?

void fun $($int& first, int &second$)\{$

first $+=$ first $+$ second;

second $+=$ second $+$ first;

$\}$

int main$()($

int list $[]=\{1,3\}$;

fun$($list $[0],$ list$[1])$;

cout $$ list list $[1]$ endl;

$\}$
