The Semester Project On Airline Reservationyou Are Required ✓ Solved

You are required to create 5 array of economy class and first class for an Airline reservation. Use a do loop asking the user for input, for example "Please select from the following options below: 1- 'First Class' 2- 'Economy' Your Choice >>". Decide the seat selection for First Class, checking if there are spots available. If a seat is assigned, print a message indicating the assigned seat. If there are no seats available in first class, check for availability in economy class and handle the reservation process accordingly. Include options for the user to reserve another seat or to exit the program, along with error handling for invalid choices.

Paper For Above Instructions

The airline reservation system serves as a fundamental example of how programming concepts can be applied to real-world scenarios. In this project, we will develop a script that manages seat reservations for an airline, focusing on first-class and economy class seating. The system will utilize arrays to store available seats and implement user interaction through a console interface using a do-while loop structure.

System Overview

The airline reservation script will function by first initializing two arrays: one for first-class seats and another for economy class seats. Each array will hold a fixed number of seats, with a simple indication of whether a seat is occupied or free. Users will be prompted to select a class, choose a seat, and manage their reservation through a loop that continues until the user opts to exit.

Implementation Steps

To begin, we declare two arrays with a predefined number of seats. For simplicity, we will define five seats for both the first-class and economy class:

let firstClassSeats = [true, true, true, true, true]; // Seats true means available
let economyClassSeats = [true, true, true, true, true]; // Seats true means available

Next, we will implement the user interface that will allow the user to select whether they want to fly first class or economy class:

do {
let choice = prompt("Please select from the following options below:\n1- 'First Class'\n2- 'Economy'\nYour Choice >>");
if (choice === '1') {
// First Class reservation logic here
} else if (choice === '2') {
// Economy reservation logic here
} else {
console.log("User Error: The choice that you entered is not valid. Please try again.");
}
} while (true);

This code snippet illustrates the prompt and validation process, helping guide the user to appropriate menu selections while handling invalid inputs robustly.

First-Class Seat Selection

When a user selects first class, the system will iterate through the first-class seat array to determine availability:

if (firstClassSeats.includes(true)) {
// Loop through seats to find an available one
for (let i = 0; i < firstClassSeats.length; i++) {
if (firstClassSeats[i]) {
firstClassSeats[i] = false; // Mark the seat as taken
console.log("Your seat in first class is number " + (i + 1) + ". Thanks for flying with us.");
break;
}
}
} else {
console.log("Unfortunately, there are no more seats in first class.");
}

This approach effectively checks the availability of seats and assigns the first open seat to the user while providing confirmation of their reservation.

Economy Class Reservation Process

If first-class seats are exhausted, the user is prompted to check economy availability. This is achieved through a similar methodology, but with different messaging:

if (economyClassSeats.includes(true)) {
// Similar loop structure for economy seats
} else {
console.log("Unfortunately, there are no more seats available in economy either.");
}
If a seat is only available in economy, prompt the user with an option for reserving another seat or ending the interaction:

“Would you like to reserve another seat? 1- Yes 2- No Your Choice >>”

Error Handling and User Interaction

To ensure a smooth user experience, thorough error handling is essential. Invalid selections invoke the error message supplied to the user. The loop continues until the user explicitly opts to terminate the program.

This functionality is crucial for maintaining user engagement and providing a user-friendly interface.

Conclusion

The airline reservation project highlights the significance of implementing logical structures and user interactions within a program. This example serves as an excellent foundation for beginners to understand arrays, loops, and user input in programming. Upon completion, individuals will have a functional console application capable of managing basic seat reservations, along with an understanding of prompt and error-handling techniques.
