Determine the output of the following program $($written in a C lilice langunge$)$ for the following parameter pasuing mechunioms:

a$)$ definitional mechaniam, varinble parameter $($call by reference$)$

b$)$ copy mechanism, value parameter

d$)$ coll by nechanism, value$-$result parameter

d$)$ call by name $($normal order evaluation$)$

int $x=12,y=10$;

printf $("\%$d $\%$d $\%$d

tswap $(++x,++y)$;

return $0$ ;

Assume $++x$ increments the variable and then gives the reference of the variable. In other words, it can be used as an l$-$value.
