How to write array in triple form? e.g. A[i] (Compiler Design)

Question

for, a=b+c,

we write,

    op     arg1     arg2

1   +       b          c
2   =       a           (1)

Then How to write A[i]

Answer 1

For the example expression:

a=b+A[i][j] 

You get the following:

op         arg1     arg2

1   index  A        i
2   index (1)       j
3   +      b       (2)
4   =      a       (3)

As @Johan suggesgted you can write [] instead of index.
