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

Consider line number 3 of the following C - program.

int main ( ) {              /* Line 1 */ 
int I, N;                   /* Line 2 */ 
fro (I = 0, I < N, I++);    /* Line 3 */ 
} 

Identify the compiler's response about this line while creating the object-module

Which of the following is NOT an advantage of using shared, dynamically linked libraries as opposed to using statically linked libraries?

Consider the syntax directed definition shown below.

Here, gen is a function that generates the output code, and newtemp is a function that returns the name of a new temporary variable on every call. Assume that ti's are the temporary variable names generated by newtemp. For the statement 'X : = Y + Z', the 3-address code sequence generated by this definition is
