Syntax-directed Translation

Consider the following ANSI C program:

int main () {
    Integer x;
    return 0;
} 

Which one of the following phases in a seven-phase C compiler will throw an error?

Consider the following grammar (that admits a series of declarations, followed by expressions) and the associated syntax directed translation (SDT) actions, given as pseudo-code

\begin{array}{lll} P & \rightarrow & D^* E^* \\ D & \rightarrow & \textsf{int ID} \{ \text{record that } \textsf{ID.} \text{lexeme is of type} \textsf{ int\}} \\ D & \rightarrow & \textsf{bool ID} \{ \text{record that } \textsf{ID.} \text{lexeme is of type} \textsf{ bool\}} \\ E& \rightarrow & E_1 +E_2 \{ \text{check that } E_1. \text{type}=E_2. \text{type} = \textsf{int}; \text{set } E.\text{type }:= \textsf{int} \} \\ E & \rightarrow & !E_1 \{ \text{check that } E_1. \text{type} = \textsf{bool}; \text{ set } E.\text{type} := \textsf{bool} \} \\ E & \rightarrow & \textsf{ID} \{ \text{set } E. \text{type } := \textsf{int} \} \end{array}

With respect to the above grammar, which one of the following choices is correct?

Consider the following grammar and the semantic actions to support the inherited type declaration attributes. Let X_1,X_2,X_3,X_4,X_5 \; and \; X_6 be the placeholders for the non-terminals D, T, L or L_1 in the following table:

Which one of the following are the appropriate choices for X_1,X_2,X_3 \; and \; X_4?

Which one of the following statements is FALSE?

Consider the following Java code fragment:

 public class While
{
    public void loop()
    {
        int x = 0;
        while(1)
        {
            System.out.println("x plus one is" +(x+1));
        }
    }
}

Which of the following statements is FALSE?

In a bottom-up evaluation of a syntax directed definition, inherited attributes can

Type checking is normally done during

A shift reduce parser carries out the actions specified within braces immediately after reducing with the corresponding rule of grammar
S \rightarrow xxW \;\text{{print "1"}}
S \rightarrow y \;\text{{print "2"}}
W \rightarrow Sz\; \text{{print "3"}}
