Step 2:

Program Design

 In program design, 

a solution is

designed using,

preferably, 

structured programming techniques, including these following:

Top-Down Program Design.

- Major processing steps called program modules are identifiers.

(Examples of top-down design)

Pseudocode.

- An outline of the logic of the program that will write.

Example of pseudocode

Flowcharts

- Graphic representations of the steps necessary to solve a programming problem.

(Flowchart symbols)

 

(Example of flowchart)

Logic structures

-Arrangements of the programming statements. there are 3 types, those are:

• Concatenation

One program statement followed by other.

(Examples of concatenation logic structure.)

• Selection (IF-THEN-ELSE) 

When a decision must be made.
Logical selection structure whereby
one of two paths
is followed according to IF,
THEN, 
and ELSE
statements in a program. 
See Selection structureS.

• Repetition (loop) (DO UNTIL and DO WHILE)

When a process is repeated until condition is true. 

DO UNTIL

- Loop structure in programming that appears

at the end of a loop.

-The DO UNTIL loop means that 

the loop statements

will be executed at least once.

-In other words, 

this program tells you

to DO option one UNTIL it is no longer true.  

DO WHILE 

- Loop structure in programming 

that appears at the end of a loop. 

-The DO UNTIL loop means that 

the loop statements

will be executed at least once.

-In other words, this program

tells you

to DO option one UNTIL it is no longer true.
