The document discusses the key stages in the program development process: 1. Planning - Identifying requirements, goals, inputs and outputs 2. Coding - Writing the source code based on the planning 3. Testing and Debugging - Thoroughly testing for errors and fixing them 4. Documentation - Providing documentation on how to use and maintain the program It also covers algorithms, flowcharts, pseudocode and data types which are important tools used in problem solving and representing programs. Algorithms define step-by-step processes, flowcharts provide graphical representation, and pseudocode describes programs using natural language.

1. Computer Programming
INTRODUCTION

2. Program Development Process
In order to create a successful program, you
need to follow the proper development process
listed.

3. Program Development Process
Planning
o first, identify the problem or the
requirements of the client
o dedicate time to think and analyze the
needed components for the program
o determine the overall goal or desired output
of the program

4. Program Development Process
Planning
o ask yourself, “Will the program produce
results?”. “Will the program calculate values?”
o define the required input and output in order
to achieve the computer program’s goals.

5. Program Development Process
Coding
o writing the source code, source code is the
actual set of programming instructions that
the computer follows.
o you should have properly planned the
intended purpose for the program and what
it should do.

6. Program Development Process
Coding
o programmers at this stage should have a
broad knowledge in the programming
language and need to make sure that the
program performs the way it is intended.

7. Program Development Process
Testing and Debugging
o errors, called “bugs”, often appear in
programs because of the details and syntax
needed for the simplest programs.
o programmers must test the program
thoroughly and fix the errors.

8. Program Development Process
Testing and Debugging
o the process of fixing errors is called
debugging.
o once a program is completely free of errors,
it is considered finished and ready to use.

9. Program Development Process
Documentation
o after the program is finished and thoroughly
tested

10. Program Development Process
Documentation includes the following:
1. necessary information about a program
such as the program description,
2. list of hardware equipment needed to run
the program,
3. operating system compatible with the
program,

11. Program Development Process
Documentation includes the following:
4. other specifications deemed necessary to
ensure smooth installation and use.
5. technical information such as where and
who created the program,
6. contact information for issues and concerns

12. Program Development Process
Documentation includes the following:
7. most importantly, instructions on the proper
use and maintenance of the program

13. Maintenance
o final stage in programming
o also the stage of updating the program
o the programmer is tasked to keep the program
running smoothly, provide updates and
improvement in consideration of development
and changes in the field it used
Program Development Process

14. Algorithms, flowcharts, data types
and pseudocodes
Problem solving is a part of our everyday life.
In computer programming, problem solving is
inevitable and it is actually one of the main
reason why a program is created.

15. Algorithms, flowcharts, data types
and pseudocodes
What is an algorithm?
 a step-by-step procedure to solve problems
Examples:
1. a guide for installing new software
2. a manual for assembling appliances
3. recipes

16. Algorithms, flowcharts, data types
and pseudocodes
What is an algorithm?
 algorithm helps in identifying decision points,
processes, essential variables to solve a
problem and the programmer can see and
determine easily the errors in a particular
process

17. Algorithms, flowcharts, data types
and pseudocodes
What is pseudocode?
o is a description of an algorithm or a
computer program using natural language
o aim is to make reading program easier, some
codes that are not essential for human
understanding is omitted

18. Algorithms, flowcharts, data types
and pseudocodes
What is pseudocode?
o Commonly used in planning out the
structure of a program or a system

19. Algorithms, flowcharts, data types
and pseudocodes
What is flowchart?
o like pseudocodes
o a description of an algorithm or a computer
program
o serves as a graphical representation
o helps in the effective analysis of the problem

20. Algorithms, flowcharts, data types
and pseudocodes
What is flowchart?
o helps in the application or program
maintenance
o provides ease in identifying potential
improvements of the system or program

21. Algorithms, flowcharts, data types
and pseudocodes
7 standard symbols:
Terminator – signifies the beginning
or the end of a program
Process – denotes a process to be
done like addition or
assignment of a variable

22. Algorithms, flowcharts, data types
and pseudocodes
7 standard symbols:
Decision – indicates when a decision
needs to be made like
yes/no or a true/false
question
Input/Output operation – signifies data
input or output

23. Algorithms, flowcharts, data types
and pseudocodes
7 standard symbols:
Arrow – indicates the logic flow’s
direction. The default is from
left to right and top to bottom
On-page connector – used to connect
flowcharts that exceed a
single page

24. Algorithms, flowcharts, data types
and pseudocodes
7 standard symbols:
Off-page connector – used the set of
hyperlinks between two pages of
a flowchart or between a
sub-process shape and a separate
flowchart page that shows the steps
in that sub-process

25. Algorithms, flowcharts, data types
and pseudocodes
Data type
o a description of a specific data that can be
stored in a variable
o the amount of memory the item occupies
