SHORT ANSWERS
8. Uninitialized variables may contain any value, usually whatever happened to be in the same memory location before the memory was allocated to that function.
9. Primarily it allows implementation to be shifted from the list to the nodes themselves.
10. The value must be unique enough that it will not be mistaken as a regular value in the list.

ALGORITHM EXERCISE
9. Declare integer count = 1

While count <= 50
Display count count = count + 1
End While
10. declare integer count count = 1 while count <= 50 display count count = count + 1 end while

PROGRAMMING EXERCISE.

7. number number_of_months number total_rainfall

display Please enter the number of years read number_of_years

for every year in number_of_years for every month in 1 to 12 display Please enter the rainfall in inches read number_of_inches total_rainfall = total_rainfall + number_of_inches end for end for

number_of_months = number_of_years * 12

display number of months is number_of_months display total rainfall is total_rainfall display average rainfall is (total_rainfall / number_of_months)

9. class Program
{
static void Main() { Console.Write("Enter number of days : "); int days; int.TryParse(Console.ReadLine(), out days); if (days == 0) return; Console.Clear(); Console.WriteLine("Day Salary"); Console.WriteLine("--- ---------"); int salary = 1; int total = 0; for(int i = 1; i <= days; i++) { Console.WriteLine("{0,-3} {1,9:c}", i, (double)salary/100); total += salary; salary *= 2; } Console.WriteLine(" ---------"); Console.WriteLine(" {0,9:c}", (double)total/100); Console.ReadKey();

10. declare Integer lowest declare Integer highest declare Integer number lowest = 1024 highest = 0 number = 0
Do While number <> -99 display("Enter a number.") Input(number) If number <> -99 And number < lowest Then lowest = number If number > highest Then highest = number
Loop
display("lowest = " & lowest) display("highest = " & highest)
