QUESTION 1

1. What is the output after the code executes? Assume there are no syntax errors and the code will compile.

   int x = 10;
   do
   {
   System.out.println ( x );
   x -= 3;
   }
   while (x > 0);

   	A.	10 7 4 1
   	B.	1 7 4 10
   	C.	10, 7, 4, 1
   	D.	1, 4, 7, 10

QUESTION 2

1. What is the value of x after the loop is done executing? Assume there are no syntax errors and the code will compile.

   int x = 10;
   do
   {
   System.out.println ( x );
   x -= 3;
   }
   while (x > 0);

   	A.	10
   	B.	1
   	C.	0
   	D.	-1
   	E.	-2

QUESTION 3

1. What is the output of the program segment? Assume there are no syntax errors and the code will compile.

   int i = 1;
   int n = 0;
   do
   {
   System.out.print( i );
   i++;
   }
   while (i <= n);

   	A.	0
   	B.	1
   	C.	-1
   	D.	2

QUESTION 4

1. What are the values of i and n after execution? Assume there are no syntax errors and the code will compile.

   int i = 1;
   int n = 0;
   do
   {
   System.out.print( i );
   i++;
   }
   while (i <= n);

   	A.	i = 1 and n = 0 when done.
   	B.	i = 0 and n = 1 when done.
   	C.	i = 2 and n = 0 when done.
   	D.	i = -1 and n = 2 when done.

QUESTION 5

1. What is the output of the following program segment?

   Assume there are no syntax errors and the code will compile.

   int x = 4;
   do
   {
   System.out.println ( x );
   x += 2;
   }
   while (x > 0);

   	A.	4 6 8 10
   	B.	0, 0, 0, 0
   	C.	Will not loop at all.
   	D.	Infinite loop.

QUESTION 6

1. What is the value of x when the loop is done? Assume there are no syntax errors and the code will compile.

   int x = 4;
   do
   {
   System.out.println ( x );
   x += 2;
   }
   while (x > 0);

   	A.	x will stay at 4.
   	B.	The loop is infinite so x will keep getting larger.
   	C.	x will be less than zero.
   	D.	x will be zero.

QUESTION 7

1. What is the output of the following program segment? Assume there are no syntax errors and the code will compile.

   int i;
   int n = 0;
   for (i = 1; i <= n; i++)
     System.out.print (i);

   	A.	There is no output.
   	B.	Output: 1
   	C.	Output: 0
   	D.	Output: -1

Answer 1

Question -1 -->

Answer is A

here, x = 10 and while loop continues till the value of x is greater than 0

so, first it will print 10 on the screen, and then the line is changed,

and then, x- = 3 ==> x = x - 3 ==> x = 10 - 3 = > x =7

so, loop will continue,

now, it will print 7 on the screen and then the line will be changed,

and then x-3 ==> x = 4.

so, loop will continue,

now, it will print 4 on the screen and then the line will be changed,

and then x-3 ==> x = 1.

so, loop will continue,

now, it will print 1 on the screen and then the line will be changed,

and then x-3 ==> x = -2

now loop will be terminated.

And so output will be -->

10

So, answer is A..
