Consider the following pseudocode:

int x $=1,$ y $=3,$ z $=5$;

void foo $($ int a $,$ int b $,$ int c $)\{$

x $=$ x $+$ b $+$ c ;

c $=$ b $-$ a ;

z $=$ x $+$ y ;

a $=$ a $+1$;

y $=$ c $-$ x $+$ b ;

printf $("\%$d $,\%$ d $,\%$ d $\backslash$ n $",$a $,$b $,$ c $)$;

$\}$

int main $()\{$

foo $()$;

printf $("\%$d $,\%$ d $,\%$ d $\backslash$ n $",$x $,$y $,$ z $)$;

$\}$

What will the code print when we call the function foo$()$ with the following parameters? If

necessary, assume that output arguments are copied back to parameters in the left$-$to$-$right

order. Please note the function foo is being called with different parameters at each of the

given question$$s below.

$1.$ foo$($x$,$x$,$y$)$ where all parameters are passed by value

$2.$ foo$($x$,$z$,$y$)$ where all parameters are passed by reference

$3.$ foo$($z$,$y$,$x$)$ where all parameters are passed by value$-$result

$4.$ foo$($x$,$y$,$y$)$ where all parameters are passed by reference
