Consider the augmented grammar with \(\{+,* , (, ), id\}\) as the set of terminals. \[ S' \rightarrow S \] \[ S \rightarrow S + R \mid R \] \[ R \rightarrow R^{\,*} P \mid P \] \[ P \rightarrow (S) \mid id \] If \(I_0\) is the set of two LR(0) items \(\{[S' \rightarrow S.], [S \rightarrow S. + R]\}\), then \(goto(\text{closure}(I_0), +)\) contains exactly \(\underline{\hspace{1cm}}\) items.
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 augmented grammar with terminals {#, @, <, >, a, b, c}.
$S' → S$
$S → S\#cS$
$S → SS$
$S → S@$
$S → <S>$
$S → a$
$S → b$
$S → c$
Let I0 = CLOSURE({ S' → • S }). The number of items in the set GOTO(GOTO(I0, <), <) is .
