Problem Based on Representation of Three Address code

Problem$-01$:

Translate the following expression to quadruple, triple and indirect triple$-$

$a+b\frac{c}{e}$uarrf$+bc$

Solution$-$

Three Address Code for the given expression is$-$

$T1=$euarrf

$T2=bc$

$T3=T\frac{2}{T}1$

$T4=ba$

$T5=a+T3$

$T6=T5+T4$

Quadruple Representation$-$

$\backslash$table$[[$Location$,$op$,$Arg$1,$Arg$2,$Result$],[(0),$uarr,e$,$f$,$T$1],[(1),x,$b$,$c$,$T$2],[(2),\frac{?}{?},$T$2,$T$1,$T$3],[(3),$x$,$b$,$a$,$T$4],[(4),+,$a$,$T$3,$T$5],[(5),+,$T$5,$T$4,$T$6]]$

Now, we write the required representations$-$
