Nested conditional statements in Go - Mini Project: Build & Apply

Nested Conditional Statements

📖 Scenario: You are creating a simple program to check a person's age and membership status to decide their ticket price for a movie theater.

🎯 Goal: Build a Go program that uses nested conditional statements to determine the ticket price based on age and membership.

📋 What You'll Learn

Create a variable age with an integer value

Create a variable isMember with a boolean value

Use nested if statements to check age and isMember

Print the correct ticket price based on the conditions

💡 Why This Matters

🌍 Real World

Nested conditions help in real life when decisions depend on multiple factors, like pricing tickets based on age and membership.

💼 Career

Understanding nested conditionals is important for writing clear decision-making code in many programming jobs.

1

Create variables for age and membership

Create a variable called age and set it to 20. Create a variable called isMember and set it to true.

Go

var age int = 20
var isMember bool = true
// Your code here

Need a hint?

Use var to declare variables with their types and assign the exact values.

2

Add a variable for base ticket price

Create a variable called ticketPrice and set it to 15.

Go

package main

import "fmt"

func main() {
    var age int = 20
    var isMember bool = true
    var ticketPrice int = 15
    // Your code here
}

Need a hint?

Use var ticketPrice int = 15 to set the starting price.

3

Use nested if statements to adjust ticket price

Use nested if statements to check if age is less than 18. Inside that, check if isMember is true. If both are true, set ticketPrice to 5. Otherwise, if age is 18 or more and isMember is true, set ticketPrice to 10.

Go

package main

import "fmt"

func main() {
    var age int = 20
    var isMember bool = true
    var ticketPrice int = 15

    // Your code here
}

Need a hint?

Use nested if inside another if and an else block to check conditions step by step.

4

Print the final ticket price

Write a fmt.Println statement to print the text "Ticket price: " followed by the value of ticketPrice.

Go

package main

import "fmt"

func main() {
    var age int = 20
    var isMember bool = true
    var ticketPrice int = 15

    if age < 18 {
        if isMember {
            ticketPrice = 5
        }
    } else {
        if isMember {
            ticketPrice = 10
        }
    }

    // Your code here
}

Need a hint?

Use fmt.Println("Ticket price:", ticketPrice) to show the final price.
