Show the output produced by each of the following program fragments. Assume that $1,j,$ and $k$ are int variables.

$($a$)$

$i=7$;$j=8$;

$i**=j+1$;

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

$($b$)$

$1=j=k=1$;

$i+=j+=k$;

printf$(\frac{?}{?}\%\frac{d}{\%}\frac{d}{\%}d,i,j,k)$;

$($c$)$

$i=1$;$j=2$;$k=3$;

$i=j-=k$;

printf$(\frac{?}{?}\%\frac{d}{\%}\frac{d}{\%}d,i,j,k)$;

$($d$)$

$i=2$;$j=1$;$k=0$;

$i**=j**=k$;

printf$(\frac{?}{?}\%\frac{d}{\%}\frac{d}{\%}d,i,j,k)$;
