What is the value assigned to each of the variables after executing the following statements?

a$)$ int a$(27),$ b$(6),$ c;

$c=b\%a$;

b$)$ int $a(27),b(6)$;

double c;

$c=\frac{a}{?}($double$)$ b;

c$)$ int $a$;

double b$(6),$ c$(18\mathrm{.}6)$;

$a=\frac{c}{b}$;

d$)$ int $b=6$;

double a$,$ c$(18\mathrm{.}6$;

$a=($int$)\frac{c}{b}$;
