Defining structures - Mini Project: Build & Apply

Defining structures

📖 Scenario: You are creating a simple program to store information about a book in a library. Each book has a title, an author, and a year of publication.

🎯 Goal: You will define a structure to hold book information, create a variable of that structure, assign values to it, and then print the book details.

📋 What You'll Learn

Define a structure called Book with three members: title (string), author (string), and year (integer).

Create a variable called myBook of type Book.

Assign the title "The C Programming Language", author "Kernighan and Ritchie", and year 1978 to myBook.

Print the book details in the format: Title: The C Programming Language, Author: Kernighan and Ritchie, Year: 1978.

💡 Why This Matters

🌍 Real World

Structures help organize complex data like records of books, employees, or products in real programs.

💼 Career

Understanding structures is essential for C programming jobs, especially in systems programming, embedded systems, and software development.

1

Define the Book structure

Define a structure called Book with three members: title and author as arrays of 50 characters, and year as an integer.

C

// Define the Book structure with title, author, and year
// Your code here

Need a hint?

Use struct Book { ... }; syntax. Use char title[50]; and char author[50]; for strings.

2

Create a Book variable called myBook

Create a variable called myBook of type struct Book.

C

struct Book {
    char title[50];
    char author[50];
    int year;
};

// Create a variable myBook of type struct Book
// Your code here

Need a hint?

Use struct Book myBook; to declare the variable.

3

Assign values to myBook

Assign the title "The C Programming Language", author "Kernighan and Ritchie", and year 1978 to the myBook variable. Use strcpy to copy strings.

C

struct Book {
    char title[50];
    char author[50];
    int year;
};

struct Book myBook;

// Assign values to myBook
// Your code here

Need a hint?

Use strcpy(destination, source); to copy strings into the structure members.

4

Print the book details

Print the book details using printf in the format: Title: The C Programming Language, Author: Kernighan and Ritchie, Year: 1978.

C

#include 
#include 

struct Book {
    char title[50];
    char author[50];
    int year;
};

struct Book myBook;

strcpy(myBook.title, "The C Programming Language");
strcpy(myBook.author, "Kernighan and Ritchie");
myBook.year = 1978;

// Print the book details
// Your code here

Need a hint?

Use printf("Title: %s, Author: %s, Year: %d\n", myBook.title, myBook.author, myBook.year); inside main().
