3. Flow Charts & PSEUDOCODES

4. Flow Chart
Flow Chart : is a diagram that shows a process , made up of boxes representing steps , decisions, input and output

9. Algorithm
Algorithm: is sequence of instructions that are followed to complete a task.
Two ways to represent Algorithm: flow chart -
pseudocode

10. Pseudocode
Psedudocode: is a way to represent the flow chart. It is a simple way to describe set of instructions that doesn’t have syntax.
In pseudocode, INPUT asks a question. Output prints a message on the screen.

11. Activity /3
Write down the Psedudocode of the following program:

12. Text Based Games

13. Text Based Games
Text based games : games that uses characters instead of images and animations.

14. Loops

15. Iteration / Loops Iteration : is the process of repeating steps.
Two ways for Iteration :
Count –controlled
Condition controlled
