Nested If: Ticket Price

Easy

Problem Description

Nested If: Ticket Price

Learning Objectives

Bloom Level: Apply

Practical Goals

  1. Implement 2-axis conditional branching with nested if statements
  2. Set boundary value (18 years) condition correctly
  3. Use boolean variable directly in condition expression
  4. Express 4-pattern fee calculation in structured code

Real-World Scenario

Scenario Type: Business

Business Context

You are developing a movie theater ticket sales system. You implement a "2-axis discount system" where prices vary by age and student ID presence.

This system is used in amusement parks, transportation, sports facilities, and many services. Master the pattern of determining fees from combinations of age category and attribute category.

Why This Matters

  • Fee calculation is a basic function of many business systems
  • 2-axis conditional branching is a frequent pattern in practice
  • Accurate boundary value processing prevents billing errors

Problem Statement

Create program that inputs age and student status to determine ticket price.

Rules:

  • 18+: 1500 yen for students, 2000 yen for general
  • Under 18: 1000 yen for students, 1200 yen for general

Input

Line 1: Age (integer)
Line 2: Student flag (true=student, false=general)

Output

Age: [age] years old
Student: [status]
Ticket price: [price] yen

Test Cases

※ Output examples follow programming industry standards

Input:
20
true

Student: false
Ticket price: 2000 yen
Input:
18
true
Expected Output:
Age: 18 years old
Student: true
Ticket price: 1500 yen
