If statement in Go - Mini Project: Build & Apply

If Statement Basics in Go

📖 Scenario: You are creating a simple program to check if a number is positive or not. This is like checking if the temperature outside is above zero to decide if you need a jacket.

🎯 Goal: Build a Go program that uses an if statement to check if a number is positive and print a message accordingly.

📋 What You'll Learn

Create an integer variable named number with the value 10

Create a boolean variable named isPositive to store if the number is positive

Use an if statement to set isPositive to true if number is greater than 0

Print "The number is positive" if isPositive is true

💡 Why This Matters

🌍 Real World

Checking conditions like this is common in programs that need to make decisions, such as validating user input or controlling game logic.

💼 Career

Understanding if statements is essential for any programming job because it helps you control the flow of your program based on different situations.

1

Create the number variable

Create an integer variable called number and set it to 10.

Go

// Your code here

Need a hint?

Use number := 10 to create the variable.

2

Create the isPositive variable

Create a boolean variable called isPositive and set it to false.

Go

package main

func main() {
    number := 10
    // Your code here
}

Need a hint?

Use isPositive := false to create the variable.

3

Use if statement to check positivity

Use an if statement to check if number is greater than 0. Inside the if block, set isPositive to true.

Go

package main

func main() {
    number := 10
    isPositive := false
    // Your code here
}

Need a hint?

Write if number > 0 { isPositive = true }.

4

Print the result

Use fmt.Println to print "The number is positive" only if isPositive is true. Remember to import fmt.

Go

package main

func main() {
    number := 10
    isPositive := false
    if number > 0 {
        isPositive = true
    }
    // Your code here
}

Need a hint?

Use if isPositive { fmt.Println("The number is positive") }.
