AP Computer Science Test - 1.3, 1.4, 5.3, 5.4, 5.5In the code segment below, assume that the int variable n has been properly declared and initialized. The code segment is intended to print a value that is 1 more than twice the value of n.
/* missing code */
System.out.print(result);
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
int result = 2 * n;result = result + 1;
int result = n + 1;result = result * 2;
int result = (n + 1) * 2;

Consider the following code segment.
int a = 5;
int b = 8;
int c = 3;
System.out.println(a + b / c * 2);
What is printed as a result of executing this code?

In the code segment below, assume that the int variables a and b have been properly declared and initialized.
int c = a;
int d = b;
c += 3;
d--;
double num = c;
num /= d;
Which of the following best describes the behavior of the code segment?
The code segment stores the value of (a + 3) / (b - 1) in the variable num.
Consider the following code segment.
int a = 5;
int b = 4;
int c = 2;
a *= 3;
b += a;
b /= c; System.out.print(b);
What is printed when the code segment is executed?

The following code segment is intended to interchange the values of the int variables x and y. Assume that x and y have been properly declared and initialized.
int temp = x;
/* missing code */
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
x = y;
y = temp;
Consider the following code segment.
num += num;
num *= num;
Assume that num has been previously declared and initialized to contain an integer value. Which of the following best describes the behavior of the code segment?
The value of num is the square of twice its original value.
Consider the following code segment, which is intended to print the digits of the two-
digit int number num in reverse order. For example, if num has the value 75, the code segment should print 57. Assume that num has been properly declared and initialized.
/* missing code */
System.out.print(onesDigit);
System.out.print(tensDigit);
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
int onesDigit = num % 10;
int tensDigit = num / 10;
Which of the following expressions evaluate to 7 ?
9 + 10 % 12
(9 + 10) % 12
9 - 2 % 12
II and III
We have an expert-written solution to this problem!
Consider the following code segment.
int x = 5;
x += 6 * 2;
x -= ;
What value is stored in x after the code segment executes?
16
Consider the following code segment, where k and count are properly declared and initialized int variables.
k++;
k++;
count++;
k--;
