Why conditional logic is needed in Go - See It in Action

Why conditional logic is needed

📖 Scenario: Imagine you are building a simple program that decides if a person can enter a club based on their age. The club only allows people who are 18 years old or older.

🎯 Goal: You will create a small Go program that uses conditional logic to check a person's age and print whether they can enter the club or not.

📋 What You'll Learn

Create a variable called age with the value 20

Create a variable called minimumAge with the value 18

Use an if statement to check if age is greater than or equal to minimumAge

Print "Access granted" if the condition is true

Print "Access denied" if the condition is false

💡 Why This Matters

🌍 Real World

Conditional logic is used in many real-world programs to make decisions, like checking age for access, validating user input, or controlling game rules.

💼 Career

Understanding conditional logic is essential for any programming job because it helps you write programs that respond differently based on data or user actions.

1

Create the age variable

Create a variable called age and set it to 20.

Go

// Your code here

Need a hint?

Use age := 20 inside the main function.

2

Create the minimumAge variable

Create a variable called minimumAge and set it to 18 inside the main function.

Go

package main

func main() {
	age := 20
	// Your code here
}

Need a hint?

Use minimumAge := 18 inside the main function.

3

Add conditional logic to check age

Use an if statement to check if age is greater than or equal to minimumAge inside the main function.

Go

package main

func main() {
	age := 20
	minimumAge := 18
	// Your code here
}

Need a hint?

Use if age >= minimumAge { ... } else { ... } and fmt.Println to print messages.

4

Print the result

Run the program and print the result using fmt.Println. The output should be Access granted.

Go

package main

import "fmt"

func main() {
	age := 20
	minimumAge := 18
	if age >= minimumAge {
		fmt.Println("Access granted")
	} else {
		fmt.Println("Access denied")
	}
	// Your code here
}

Need a hint?

Run the program to see the printed message.
