a) What is the output of the following code?

int n = 5371; int digit = 0; int sum = 0; while (n > 0) { digit = n % 10; sum = sum + digit; n = n / 10; } System.out.println(sum); 

b) How many times will the System.out.print(*); statement execute inside of the following nested for-loops?

int j, k; for (j = 0; j <= 3; j++) for (k = 3; k >= j; k--) System.out.print("*");

c) A data verification loop is a loop that asks the user to input a value within a restricted range repeatedly until the user has input a value within the requested range. Fill in the blanks to complete the data verification loop below that that accepts an int value for x within the range 0 and 100 (both 0 and 100 are valid values).

Scanner in = new Scanner(System.in); int x = _____; // initialize x while (______________________________) { // insure that the loop body executes until x is valid System.out.print("Enter a value from 0 to 100 :"); x = in.nextInt(); }
