For a C program accessing X[ i ] [ j ] [ k ], the following intermediate code is generated by a compiler. Assume that the size of an integer is 32 bits and the size of a character is 8 bits.
t0 = i * 1024
t1 = j * 32
t2 = k * 4
t3 = t1 + t0
t4 = t3 + t2
t5 = X[t4]

Consider the following translation scheme.
$$\eqalign{ & S \to ER \cr & R \to *E\left\{ {pr{\mathop{\rm int}} ('*');} \right\}R\,|\,\varepsilon \cr & E \to F + E\left\{ {pr{\mathop{\rm int}} (' + ');} \right\}\,|\,F \cr & F \to S\,|\,id\,\left\{ {pr{\mathop{\rm int}} (id.value);} \right\} \cr} $$Here id is a token that represents an integer and id.value represents the corresponding integer value. For an input '2 * 3 + 4' this translation scheme prints
