Suppose that the input is:
38 35 71 14 -1
What is the output of the following code? Assume all variables are properly
declared.
num = console.nextInt();
sum = num;

8.

while (num != -1)
{

num = console.nextInt();
sum = sum + num;

}

System.out.println("Sum = " + sum);

Suppose that the input is:

9.

while (num != -1)
{

sum = sum + num;
num = console.nextInt();

}

System.out.println("Sum = " + sum);

10. Correct the following code so that it finds the sum of 10 numbers:
sum = 0;

while (count < 10)
num = console.nextInt();
sum = sum + num;
count++;

11. What is the output of the following program?

{

public static void main(String[] args)
{

int x, y, z;

x = 4;
y = 5;
z = y + 6;
