language is in c.

Suppose you want to define variables a and b of type int, variable p of type pointer to int, and variable x of type pointer to pointer to int. Which of the following declarations are correct? (Check all the correct answers.) int a; int b; int a; int b; int *p; int **x;. You int *p; int **x; w int a, int b, int *p, int ***; int a; b; * p; **q; int a, b, *p, **x; If y is of type int, which type should x be for the following assignment to be correct? *x = &Y; int ** int * int O void What value does the following program return? int main(void) { int a = 2; if (!a) return 1; return 0; O The program doesn't compile. O The program crashes. O1 !a is equivalent to a==0. What does the following function return when called with argument 3? int f(int x) { int a = 2; if (x
