Three address code for the above code segment:

I0	func begin main
I1	a:=1
I2	z:=0
I3	Label .L0
I4	if a<=10 goto .L1
I5	goto .L2
I6	label .L1
I7	_t0:=2*a
I8	_t1:=4*a
I9	_t2:=&b
I10	_t2[_t1]:=_t0; // assuming the (size of int) = 4
I11	goto .L0
I12	label .L2
I13	_t3:=a
I14	_t4:=4*a
I15	_t5:=&b
I16	_t6:=_t5[_t4]
