Here is the pseudo code: START INPUT numOfPoster, type IF type = "colored" AND numOfPoster <= 500 payment = 2000 ELSE IF type = "colored" AND numOfPoster > 500 payment = 2000 + (numOfPoster - 500) * 2 ELSE IF type = "black and white" AND numOfPoster <= 500 payment = 1000 ELSE payment = 1000 + (numOfPoster - 500) * 1.5 PRINT payment END

1. PROBLEM SOLVING
 Problem solving involves:
 Analysis
 Algorithm or pseudo code or flow chart or combination
of them.

2. PROBLEMS ANALYSIS
 Identify problems:
 Input
 Output
 Process
INPUT PROCESS OUTPUT

3. ALGORITHM
 Algorithm
 Any computing problem can be done by executing a
series of actions in a specific order.
 A procedure for solving a problem in terms of the
actions to be executed and the order in which these
actions are to be executed is called an algorithm.
 Is a logical solution that is inline with our daily language
or mother tongue language.

4. ALGORITHM
Start
1. Set sum = 0 and average = 0
2. Read 3 numbers: nom1, nom2, nom3
3. Add 3 numbers
4. Calculate the average, average = (sum)/3
5. Print 3 numbers(nom1, nom2, nom3) and
the average
End

5. PSEUDO CODE
 Pseudo code
Is an artificial and informal language
Usually it is use English language
Quite similar to programming language
The purpose of pseudo code is to make
humans who do not understand
computer programming can easily
understand the flow of the problem
solving.

6. PSEUDO CODE
START
SET sum = 0, average = 0
INPUT nom1, nom2, nom3
sum = nom1 + nom2 + nom3
average = sum / 3
PRINT nom1, nom2, nom3
PRINT average
END

7. FLOW CHART
 Flow Chart
 It is represents by using geometry shapes with
connected line
 Use a standard symbol

8. FLOW CHART
TERMINAL
Indicates the beginning or end of an algorithm
PROCESS
Indicates an input computational or data
manipulation.
INPUT / OUTPUT
Indicates an input or output operation

9. FLOW CHART
DECISION
Indicates a decision point in the algorithm
CONNECTOR
Indicates an entry to or exit from another
part of the flowchart
FLOW LINES
Used to connect the flowchart symbols and
indicate the logic flow
LOOP
Indicates the initial, final and increment
values of a loop

10. CONTROL STRUCTURE
•It’s a technique in producing program logic which is simple and
easy to understand
•.It show the problem solution whether it’s a jujukan, selection
or repetition control structure or the combination of two or
three control structure.
•Every programmer should analyze the problem to indentify the
suitable control structure that must use .

11. CONTROL STRUCTURE
 There are three type of control structure :
 Sequence
 Selection
 Repetition

12. SEQUENCE CONTROL STRUCTURE
 Sequence control structure used when a problem is
solved sequentially from start to end. Every
instruction is perform once only. It used to solve
problems that easy. This solution does not involve
any condition and there is no repetition of
instructions.

13. CONTROL STRUCTURE :
in
Process 1
Process 2
Process 3
out

14.  Example 1:
Kebajikan FTMK mengenakan yuran sebanyak 1%
dari jumlah gaji setiap ahli untuk tabung
kebajikannya. Lukiskan cartalir dan tuliskan
aturcara untuk mencetak nama dan yuran yang
diterima dari seorang ahlinya.

15. Anaylze :
input : name, salary
process : fee = salary * 1%
output : fee

16. FLOWCHART :
start
end
Input
salary
Print fee
Fee = 1% * salary

17. # include <iostream.h>
// Program to calculate and display club fee
main ()
{ // Initialization of variables
char name [15]; // staff name
float salary =0, fee=0; // salary and fee
// Data entry section
cout << “please enter staff name";
cin >> name;
cout << “please enter salary ";
cin >> gaji;
// Processing section
fee = salary *.01;
// Printing Section
cout << “Staff name “<<name<<endl;
cout << "n The club fee is RM"<<fee;
// end of programme
return 0;
}

18. EXAMPLE 2
 Assume N number of students have to take
MTS1033 course in UPSI and each student is
required to buy C++ book with a price of RMX. The
publisher will get 10% profit for each book that is
sold. Write a program to calculate and print the
profit that earned by the publisher.

19. CONTROL STRUCTURE - SELECTION
 Selection control structure is used when the execution of
instructions are depend on the result of a decision/selection that
the program must make
if ..else Statement
Format :
if <(condition)> statement1;
else statement2;
or
if <(condition)> no semicolon
statement1;
else no semicolon
statement2;

20. SELECTION CONTROL STRUCTURE -FLOWCHART
condition
Statement 2
statement 1
y
n
If the value of condition is true, then statement1 will be
executed, otherwise statement2 will be executed

21. SELECTION CONTROL STRUCTURE -FLOWCHART
syarat
Kenyataan 1
y
t
Selection without else statement
if <(condition)> or if <(condition)> statement1
{ statement1
statement2
:
}

22. CONTROL STRUCTURE -SELECTION
 Cost of printing price for coloured poster is RM2000
for the first 500 pieces and RM1000 for black and
white poster. For each piece above then 500, the
cost is RM2 for coloured and RM1.50for the black
an white. Write a pseudo code and a programme to
calculate payment that need to be paid by a
customer.
