INPUT-PROCESS-OUTPUT (IPO) MODEL IN PROJECTS
The IPO model helps structure programs by breaking them into three main parts:
Input: Collecting user data (e.g., typing a name or clicking a button).
Process: Performing calculations or logic based on the input.
Output: Displaying results to the user.
BUILDING APPS WITH VARIABLES AND CONDITIONS
In App Lab, we can create functional apps using variables and conditional logic. Some
project ideas include:
Quiz App: Store user answers in variables and check if they are correct.
Simple Game: Keep track of a player’s score and decide if they win or lose.
Weather App: Take user input (temperature) and display a message based on
conditions.
Example: Quiz App Code
onEvent("button1", "click", function() {
var answer = getText("inputBox");
if (answer == "Paris") {
setText("resultLabel", "Correct!");
