Program is a piece of software well defined and easy to understand. There are 2 stage to developing a program, define and analyse.
1 Defined problem by using IPO chart.
2 Analysis the problem.
Outline solution
Action
List variable and major step.
The analysing tool we use:
Pseudo code (English language structure).
Algorithm
Deskcheck
Flow charts and
Structure chart (function).

 

3 approaching type of structure Programming:

- Top down
by broken down into steps.
- Modular
Group task with the same function.
Using function and library.
- Structure theorem
Use control structure.

 

 

 

Implementation
- Code
- Run
- Test
- Documentation
- Summary of tools

Maintenance:
- Administration
- Backup

Pseudo code sample of calculate high and low salary

START
SET LOW_SALARY TO ZERO
SET HIGH_SALARY TO ZERO
DO WHILE(SALARY = XXX)
PROMP FOR SALARY
GET SALARY
IF SALARY > HIGH_SALARY
HIGH_SALARY = SALARY
END IF

IF SALARY < LOW_SALARY
LOW_SALARY = SALARY
END IF
PROMP FOR SALARY
END DO
DISPLAY LOW_SALARY
HIGH_SALARY
END
