1.0 Problem Solving (REPETITION)
1.2 Problem Analysis
 Identity input, process, and output from a given problem
1.3 Design a Solution
 Define Algorithm (Pseudocode & Flowchart)

 Solve a given problem using Pseudocode
 Solve a given problem using Flowcharts

1. The use of appropriate control structure is very important when writing a computer
program.
Identify the suitable control structure to solve the following problems:

Problem Control Structure

a. Check whether a staff is entitled to get Selection Control Structure
an overtime pay or not.

b. Get the average marks obtained by students in Repetition Control Structure
the whole matriculation batch. with counter control

c. Calculate the fuel price that needs to be paid by Sequence Control Structure
a customer at a petrol station.

d. Enter the items purchased by a customer one by Repetition Control Structure
one until the null value is entered. with sentinel control

e. Give 10%discount from the total price for a Repetition Counter control
homeless customer. with Accumulator

2. Before writing a program to solve a particular problem, it is essential to have a thorough
understanding of the problem and carefully plan the approach to solve the problem.
(a) Define algorithm.

An algorithm is a step-by-step instruction that will transform the input into
the output.

(b) Describe two (2) of the techniques that you have answered in question 2(a).

Pseudocode An artificial, informal language used to develop algorithms
Flowchart which also similar to everyday English.

3. Explain repetition or looping.

Repetition or looping allow to repeat one or more instructions until some conditions is
met.

4. Define counter controlled.

Counter-controlled repetition is often called definite repetition because the number of
repetitions is known before the loop begins executing.

5. List the 4 tasks associated with counter controlled:

i. Counter-Loop Name ii. Initial Value

iii. Condition iv. Update Value

6. Define sentinel controlled.

Sentinel controlled repetition is sometimes called indefinite repetition because it is not
known in advance how many times the loop will be executed.

7. List the 3 tasks associated with sentinel controlled:
i. Initial value of sentinel control variable ii. Condition to test sentinel control
variable
iii. Update the value of sentinel control
variable

8. Draw a symbol used to represent a repetition structure’s condition in a flowchart.

33. Puan Marina is a programming lecturer at Kolej Teknologi Kedah. Due to the high failure
rate in her class, she intends to find the total number of students who have passed in the
examination. The passing mark is 40 marks and above. There are 98 students in her class.

Input Process Output

students who have passed in the have passed

examination based on marks for 98
students.

while (student <= 98)
Read marks
if (marks >= 40)
Total Pass = Total Pass + 1
end if
student = student + 1

34. A former secretary had left her
job and decided to sell textbooks. Assume the book is sold at different price on each day.
Calculate how much money that will be earned after a week.

Input Process Output

price, Calculate total price book sold based on total price
number of book price and number of books for 7 days.

Pseudocode

Start
day = 1
total price = 0 total = price x qtty

while (day <= 7) total price = total price + price

Read price, number of book

total price = total price + (price x number of book)
day = day + 1

end while

35. The sales manager at MN Company wants to display the price based on a product ID she
enters. Assume there are ‘n’ items. The valid product IDs and their corresponding prices
are shown here. For each item, if the product ID is not valid, the program should display
the “Invalid product ID” message.
