$```$

if $($n

printf$("$n is between $1$ and $10$

$```$

for $($i $=5,$ j $=$ i $-1$; i $>0,$ j $>0$; $--$i$,$ j $=$ i $-1)$

printf$("\%4$d $",$ i$)$;

$```$

$6.(5$ points$)$ What output the following code fragment will produce? Explain in detail.

$```$

sum $=0$;

for $($i $=1$; i ; i$++)\{$

if $(!($i $\%3))$

continue;

$7.(3$ points$)$ Rewrite the following loop so that its body is empty. Explain your answer.

$\backslash [$

$\backslash$begin$\{$array$\}\{$l$\}$

$\backslash$text $\{$ for $\}($n$=0$ ; m$>0$ ; n$++)\backslash \backslash$

m $/=2$ ;

$8.(4$ points$)$ The following function is supposed to return true if any element of the array a has the value $0$ and false if all elements are nonzero. Sadly, it contains an error. Find the error and show how to fix it:

$```$

bool has$\_$zero$($int a$[],$ int n$)$

$\{$

int i;

for $($i $=0$; i $$ n; i$++)$

if $($a$[$i$]==0)$

return true;

else

return false;

$\}$

$```$

Explain your answer in detail.
