Given the code fragment:
int j=0, k =0;
for (int i=0; i < x; i++) {
do {
k=0;
while (k < z) {
k++;
System.out.print(k + ” “);
}
System.out.println(” “);
j++;
} while (j< y);
System.out.println(“—-“);
}
What values of x, y, z will produce the following result?
1 2 3 4
1 2 3 4
1 2 3 4
——1 2 3 4
A.
X = 4, Y = 3, Z = 2
B.
X = 3, Y = 2, Z = 3
C.
X = 2, Y = 3, Z = 3
D.
X = 4, Y = 2, Z = 3
E.
X = 2, Y = 3, Z = 4
Explanation:
Z is for the innermost loop. Should print 1 2 3 4. So Z must be 4.
Y is for the middle loop. Should print three lines of 1 2 3 4. So Y must be set 3.
X is for the outmost loop. Should print 2 lines of —-. So X should be 2.
Question is wrong!
What values of x, y, z will produce the following result?
1 2 3 4
1 2 3 4
1 2 3 4
——1 2 3 4
Correct would be:
1 2 3 4
1 2 3 4
1 2 3 4
