Question 1
errors can be syntax errors or logic errors (the code works, but not as intended).

in the guess my number game, there is a lower limit and an upper limit for the range of possible numbers to guess. if the lower limit were exclusive and the upper limit exclusive, which expression would properly generate values for the secret number?

(int)(math. random() * (upper − lower) ) + lower
(int)(math. random() * (upper − lower + 1) ) + lower
(int)(math. random() * (upper − lower) ) + lower + 1
(int)(math. random() * (upper − 1 − lower) ) + lower + 1
(int)(math. random() * (upper − lower + 1) ) + lower − 1

question 2
errors can be syntax errors or logic errors (the code works, but not as intended).

which of the following is equivalent to while( ! (userguess == secretnumber) )?

while( userguess ! = secretnumber )
while(userguess < secretnumber || userguess > secretnumber)
while( userguess < secretnumber & & userguess > secretnumber)
i only
ii only
iii only
i and ii only
i and iii only

question 3
errors can be syntax errors or logic errors (the code works, but not as intended).

after execution of the following code segment, what will be displayed?

int x = 15;
while(x > 0)
{
x −= 6;
}
system. out. println(x);

−6
−3
0
3
15

question 4
errors can be syntax errors or logic errors (the code works, but not as intended).

what conclusion can be made about the state of the program when the while loop terminates? assume answer is a declared and initialized string.

while(! answer. equals( "n"))
{
// code not shown
}

the value of answer is n
the value of answer is n or n
the value of answer is not n
the value of answer is y
nothing can be determined

question 5
errors can be syntax errors or logic errors (the code works, but not as intended).

in the guess my number program, the user continues guessing numbers until the secret number is matched. assuming numguesses is initialized to 1, how would the while statement be modified to include an extra criterion limiting the number of guesses to 15?

while( (userguess == secretnumber) || numguesses < 14 )
while( (userguess== secretnumber) & & numguesses < = 15 )
while( ! (userguess == secretnumber) || numguesses < 15 )
while( ! (userguess == secretnumber) & & numguesses < = 15 )
while( ! (userguess == secretnumber) & & numguesses < 15 )
