1. By indenting the statements in the body of the loop you visually set them apart from the surrounding code. 2. Pretest loops test its condition before performing an iterations and posttest loops perform an iteration before testing its conditions. 3. A condition-controlled loop uses a true/false to control the number of times it repeats. 4. A count-controlled loop repeats a specific number of times. 5. Using the counter variable, the loop typically performs the following three actions: initialization, test, and increment.

1. //Declare local variables
//Ask user for number to be multiplied
Declare Integer number = 0
Declare Integer product
Set keepGoing = “y”
While keepGoing = “y” Display “Enter a number to be multiplied by 10: “ Input number Set product = number * 10 Display “Enter y to continue again”
End While 2. //Declare Local Variables
//Ask user to enter 2 numbers
Declare Integer number1 = 0
Declare Integer number2 = 0
Declare Integer sum
Declare String keepGoing = “y”
Do
Display “Please enter your 1st number: “
Input number1
Display “Please enter your 2nd number: “
Input number2
Set sum = number1 + number2
Display “The sum of those numbers is “, sum
Display “Do you wish to repeat this process? Enter y to continue...”
While keepGoing = “y”
Input keepGoing

7. Do-While Loop:
Declare Integer x = 1
Declare String keepGoing = “y”
Do
Input x
Display “Do you wish to repeat?”
While keepGoing = y
End While 8. While loop:
Declare String sure
While sure != “Y” AND sure != “y” Display “Are you sure you want to quit?” Input sure

1. //Declare local variables
//Ask user for number of bugs on each day
Declare Integer counter = 1
Declare integer day = 1
Declare Integer totalBugs
For counter = 1 to 7 Display “Enter the total number of bugs collected today: “ Input day Set totalBugs = day + day
End For
Display “The total number of bugs collected in 7 days is “, totalBugs 3. //Declare variables to hold each number
//Ask user for amount budgeted for a month and amount of expenses for a month
Declare Integer monthBudget
Declare Integer monthExpenses
Declare Integer total = 0
Declare Integer counter
For counter = 1 to 5 Display “Enter monthly budgeted amount: “ Input monthBudget Display “Enter monthly expenses amount: “ Input monthExpenses Set total = total + monthExpense
End For
Display “Your total expenses is “, total 4. //Declare local variables
//Ask user for positive numbers and a negative at the end of the positives
Declare Integer pNumber = 0
Declare Integer tNumber = 0
Declare Integer counter = 1
While pNumber !< 0 Display “Enter positive number: ” Display “Enter negative number to end: ” Input pNumber
End While
Set tNumber = pNumber +pNumber
Display “The total of the number you entered is “, tNumber
