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 the following C code segment.

for (i = 0; i < n; i++) 
  { 
      for (j=0; j < n; j++) 
      { 
          if (i%2) 
          { 
           x += (4*j + 5*i); 
           y += (7 + 4*j); 
          } 
       } 
  } 

Which one of the following is false?

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

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
