Comparison operators in Kotlin - Mini Project: Build & Apply

Comparison Operators in Kotlin

📖 Scenario: You are helping a store manager compare product prices to decide which items are cheaper or more expensive.

🎯 Goal: Build a Kotlin program that compares two product prices using comparison operators and shows the results.

📋 What You'll Learn

Create two variables with exact prices

Create a variable to hold a threshold price

Use comparison operators to compare prices with the threshold

Print the comparison results clearly

💡 Why This Matters

🌍 Real World

Comparing prices helps shoppers and store managers decide which products are cheaper or more expensive.

💼 Career

Understanding comparison operators is essential for decision-making logic in software development.

1

Create product price variables

Create two variables called priceA and priceB with values 150 and 200 respectively.

Kotlin

# Create variables priceA and priceB with values 150 and 200
// Your code here

Need a hint?

Use val to create variables and assign the exact numbers.

2

Add a threshold price variable

Create a variable called threshold and set it to 180.

Kotlin

val priceA = 150
val priceB = 200
// Create a variable threshold with value 180
// Your code here

Need a hint?

Use val threshold = 180 to create the variable.

3

Compare prices with threshold

Create two Boolean variables called isPriceALess and isPriceBMore. Set isPriceALess to the result of priceA < threshold and isPriceBMore to the result of priceB > threshold.

Kotlin

val priceA = 150
val priceB = 200
val threshold = 180
// Create isPriceALess and isPriceBMore using comparison operators
// Your code here

Need a hint?

Use < and > operators to compare values.

4

Print the comparison results

Print the values of isPriceALess and isPriceBMore using two separate println statements.

Kotlin

val priceA = 150
val priceB = 200
val threshold = 180
val isPriceALess = priceA  threshold
// Print isPriceALess and isPriceBMore
// Your code here

Need a hint?

Use println(isPriceALess) and println(isPriceBMore) to show the results.
