Exam 5: Control Structures II: Repetition

The control statements in the for loop include the initial expression, logical expression, and update expression.

A while loop is a post-test loop.

In the case of an infinite while loop, the while expression (that is, the loop condition) is always true.

The output of the Java code, assuming that all variables are properly declared, is: 2 3 4 5 6.n = 2; while (n >= 6) { System.out.print(n + " "); n++; } System.out.println();

Which of the following is true about a while loop?

The loop condition of a while loop is reevaluated before every iteration of the loop.

The following for loop executes 21 times. (Assume all variables are properly declared.)for (i = 1; i <= 20; i = i + 1): System.out.println(i);

boolean found = false; Int num; Int square;while (!found) { Num = console.nextInt(); Square = num * num; If (square > 40) Found = true; }The above code is an example of a(n) ____ loop.

ch = inFile.next().charAt();while (inFile.hasNext()) { System.out.println(ch); Ch = inFile.next().charAt(); }The above code is an example of a(n) ____ loop.

What is value of x after the following code executes?int x = 0; Int i;for (i = 0; i < 5; i++) X = 3 * x + i;

int i;for (i = 0; i <= 10; i++) System.out.println("*"); System.out.println("!");Which of the following is the update expression in the for loop above?

Which executes immediately after a continue statement in a for loop?

Control variables are automatically initialized in a loop.

int x = 27; Int y = 10;do X = x / 3; While (x >= y);What is the final value of x in the code above?

The output of the following Java code is: Stoor.int count = 5; System.out.print("Sto");do { System.out.print('o'); count--; } while (count >= 5);System.out.println('r');

A break statement is legal in a while loop, but not in a for loop.

What is the output of the following Java code?int num = 15; While (num > 0) Num = num - 3; System.out.println(num);

What is the value of counter after the following statements execute?counter = 1; While (counter<30) Counter = 2 * counter;

In the case of the sentinel-controlled while loop, the first item is read before the while loop is entered.

int i;for (i = 0; i <= 10; i++) System.out.println("*"); System.out.println("!");Which of the following is the initial expression in the for loop above?
