Assume the following C variable declaration

int * A[10], B[10][10];

Of the following expressions

I. A[2]
II. A[2] [3]
III. B[1]
IV. B[2] [3]

Which will not give compile-time errors if used as left hand sides of assignment statements in a C program?

The following program fragment is written in a programming language that allows global variables and does not allow nested declarations of functions.

global int i = 100, j = 5;
void P(x) {
    int i = 10;
    print(x + 10);
    i = 200;
    j = 20;
    print (x);
}
main() {
    P(i + j);
}

If the programming language uses dynamic scoping and call by name parameter passing mechanism, the values printed by the above program are

Consider the $$NFA$$ $$M$$ shown below.

Let the language accepted by $$M$$ be $$L.$$ Let $${L_1}$$ be the language accepted by the $$NFA$$, $${M_1}$$ obtained by changing the accepting state of $$M$$ to a non accepting state and by changing the non accepting state of $$M$$ to accepting states. Which of the following statements is true?

The regular expression $${0^ * }\left( {{{10}^ * }} \right){}^ * $$denotes the same set as
