Assume, if the values of a and b integer type pointer variables are $10$ and $20$ respectively before swapping, then the values of a and b are $20$ and $10$ respectively after swapping. $4\mathrm{.}03$ #include #include int main$()\{$ int $*$a$,*$b$,$ temp; a$=($int$*)$ malloc$($sizeof$($int$))$; b$=($int$*)$ malloc$($sizeof$($int$))$; scanf$(\%$d$\%$d$,$ &a$,$ &b$)$; printf$(\%$d $\%$d
