Boolean type in Rust - Mini Project: Build & Apply

Boolean type

📖 Scenario: Imagine you are creating a simple system to check if a store is open or closed based on a boolean value.

🎯 Goal: You will create a boolean variable to represent the store status, then use it to print if the store is open or closed.

📋 What You'll Learn

Create a boolean variable called is_open with the value true

Create a boolean variable called is_closed with the value false

Use an if statement to check is_open and print "Store is open" if true

Use an else statement to print "Store is closed" if is_open is false

💡 Why This Matters

🌍 Real World

Booleans are used everywhere in programming to represent yes/no, on/off, or true/false states, like checking if a user is logged in or if a device is connected.

💼 Career

Understanding boolean types and conditional statements is essential for any programming job because they control the flow of decisions in software.

1

Create boolean variables

Create a boolean variable called is_open and set it to true.

Rust

# Your code here

Need a hint?

Use let to create a variable and true for the boolean value.

2

Add second boolean variable

Add a boolean variable called is_closed and set it to false below is_open.

Rust

fn main() {
    let is_open: bool = true;
    # Your code here
}

Need a hint?

Use let and false to create the second boolean variable.

3

Use if statement to check store status

Use an if statement to check if is_open is true. Inside the if, write println!("Store is open");. Add an else block that prints "Store is closed".

Rust

fn main() {
    let is_open: bool = true;
    let is_closed: bool = false;
    # Your code here
}

Need a hint?

Use if is_open { ... } else { ... } to decide what to print.

4

Print the store status

Run the program to print the store status based on the is_open boolean variable.

Rust

fn main() {
    let is_open: bool = true;
    let is_closed: bool = false;
    if is_open {
        println!("Store is open");
    } else {
        println!("Store is closed");
    }
    # Your code here
}
