Introduction Of Algorithms
Definition and Example

What is the Definition of Problem?
Question or set of works that
must be done with human.

Algorithm and
Programming can
solve the problems

Some Terms in Programming
• Program is implementation of ALGORITHM that
was made from one programming language.
• Programming language is notation that was used
in ALGORITHM NOTATION to communicate with
computers.
• Programmers are people who made the
programs with ONE OR MANY programming
languages.

Types of Programming Languages
• High Level
• Middle Level
• Low Level

Build the Program
• Problem Definition
• Requirements Analysis
• Build the algorithms
• Coding
• Testing and Debugging
• Maintenance
• Documentation

What is Algorithm?
Sequence of steps to solve
the problems.

How to Make Scramble Egg:
• Pour oil into skillet.
• Heat oil.
• Break the eggs and pour into the hot oil.
• Fry it
• Serve on a plate

Exercise 1
Turn the process of exchange value with variable
into:
• Descriptive Analysis
• Flow Chart
• Pseudo Code

Exercise 2
Make algoritm for exchange value without variable
(this case only suitable for integer) in:
• Flow Chart
• Pseudo Code

Exercise 3
Make algoritm for basic arithmetic operation (add,
substract, multiply, and divide) in:
• Flow Chart
• Pseudo Code
