The following program generates an error. Why?

void PrintSum$($int num$1,$ int num$2)$ it printf$("\%$d$",$ num$1+$ num$2)$;

$?$

int main$($void$)\{$

int $y$;

$y=Pr\frac{{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}}{S}um(4,5)$;

return $0$;

$\}$

The values $4$ and $5$ cannot be passed directly to PrintSum$()$

main$()$ has a return statement that returns the value $0$

PrintSum$()$ has void return type, so cannot be assigned to a varia

The void function is missing a "return:" statement
