What we will Learn today? Understand Flow chart – Algorithm and Pseudocode Understand text based games Understand Loops

Flow Charts & PSEUDOCODES

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

Flow Chart

Activity / 1 Complete the flow chart using the following words: OUTPUT Start Complete the flow chart using the following words: OUTPUT INPUT START STOP DECISION Output Stop

Response stored in variable Activity /2 ------------------- ---------------- Enter a number Response stored in variable --------------- Is the num > 0 “number is positive” “number is negative” Yes No Complete the flow chart using the following words: OUTPUT INPUT START STOP DECISION

Response stored in variable Activity /2 Enter a number Response stored in variable Decision Is the num > 0 “number is positive” “number is negative” Yes No Start Complete the flow chart using the following words: OUTPUT INPUT START STOP DECISION Output Input Output Output Stop

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

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.

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

Text Based Games

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

Loops

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