Multiple input and output in C++ - Mini Project: Build & Apply

Multiple Input and Output in C++

📖 Scenario: You are creating a simple program to collect and display information about a book. This is like filling out a form with multiple pieces of information and then showing it back to the user.

🎯 Goal: Build a C++ program that takes multiple inputs from the user (title, author, and year) and then prints them out clearly.

📋 What You'll Learn

Use std::string variables for text inputs

Use int variable for the year

Use std::cin to get inputs

Use std::cout to display outputs

Handle multiple inputs and outputs in a clear format

💡 Why This Matters

🌍 Real World

Collecting and displaying multiple pieces of information is common in programs like forms, surveys, and data entry systems.

💼 Career

Understanding how to handle multiple inputs and outputs is essential for building interactive applications and user interfaces.

1

Create variables for book information

Declare three variables: a std::string called title, a std::string called author, and an int called year.

C++

#include 
#include 

int main() {

    // Declare variables title, author, and year
    // Your code here

    return 0;
}

Need a hint?

Use std::string for text and int for numbers.

2

Get input from the user

Use std::cout to ask the user to enter the book's title, author, and year. Then use std::getline(std::cin, title) for the title and author, and std::cin >> year for the year to get the inputs.

C++

#include 
#include 

int main() {
    std::string title;
    std::string author;
    int year;

    // Ask and get title, author, and year from user
    // Your code here

    return 0;
}

Need a hint?

Use std::getline for strings to allow spaces, and std::cin for the integer.

3

Display the collected book information

Use std::cout to print the book's title, author, and year in a clear format. Use multiple std::cout statements or one combined statement.

C++

#include 
#include 

int main() {
    std::string title;
    std::string author;
    int year;

    std::cout > year;

    // Print the book information
    // Your code here

    return 0;
}

Need a hint?

Use std::cout with the << operator to print variables and text.

4

Run and display the final output

Run the program and print the book information exactly as shown: first the prompt lines, then the book information with labels Title, Author, and Year each on its own line.

C++

#include 
#include 

int main() {
    std::string title;
    std::string author;
    int year;

    std::cout > year;

    std::cout << "\nBook Information:\n";
    std::cout << "Title: " << title << "\n";
    std::cout << "Author: " << author << "\n";
    std::cout << "Year: " << year << "\n";

    // Your code here

    return 0;
}

Make sure your output matches the prompts and labels exactly, including new lines.
