State two (2) basic processes involved in counter-controlled repetition

• looping

• update counter

• condition

• selection

Draw the symbol used to update counter in repetition control structure

• 
• 
• 
• 

Describe sentinel-controlled structure

• uses a counter value to stop a loop.

• uses a sentinel value to stop a loop.

• uses a special value that marks the end of a list of values.

• use special value to update counter

Describe counter controlled structure

• the number of repetitions is known before the loop begins executing

• you doesn't know exactly the number of times the loop has to be executed

• you know exactly the number of times the loop has to be executed

• a special value that is used to terminate a loop

Identity basic processes involved in counter-controlled repetition based a statement below

• Condition

• Updating

• Initialize

• priming value

Base on statement b is consider as ?

• update counter

• Initialization

• Condition

• counter controller

A program will display “Think before you trash it.” for 10 times. Assume that you will use a counter variable named i. Write the initialization expression

• i <=10

• i=i+1

• i = 10

• i = 1

The program will display a series of number from 5 to 23 in descending order.Write the condition or test expression.

• number = 5

• number =23

• number < 24

• number <=23

Identify a from flowchart design

• counter = counter + 1

• Read price

• Read a

• Read price

Identify the suitable types of repetition control structure to solve the following problems:         

              Enter the items purchased by a customer one by one until the null value is entered.

• selection

• sequence

• sentinel

• counter controller
