Naming conventions in C# - Mini Project: Build & Apply

Naming conventions in C#

📖 Scenario: You are creating a simple program to store information about a book in a library system. To keep your code clear and easy to read, you will use proper naming conventions in C#.

🎯 Goal: Learn how to name variables, constants, and methods in C# using the correct naming conventions.

📋 What You'll Learn

Create variables with camelCase naming

Create constants with PascalCase naming

Create a method with PascalCase naming

Use meaningful names following C# conventions

💡 Why This Matters

🌍 Real World

Naming conventions help developers read and understand code quickly, especially in team projects or large codebases.

💼 Career

Following naming conventions is a basic skill expected in software development jobs to write clean, professional code.

1

Create variables with camelCase naming

Create three variables named bookTitle, authorName, and numberOfPages with these exact values: "The Great Gatsby", "F. Scott Fitzgerald", and 180 respectively.

C Sharp (C#)

# Create variables bookTitle, authorName, and numberOfPages with the given values
// Your code here

Need a hint?

Remember, variables in C# use camelCase, starting with a lowercase letter.

2

Create constants with PascalCase naming

Add two constants named MaxBooksAllowed and LibraryName with values 5 and "City Library" respectively. Use the const keyword.

C Sharp (C#)

string bookTitle = "The Great Gatsby";
string authorName = "F. Scott Fitzgerald";
int numberOfPages = 180;
// Add constants MaxBooksAllowed and LibraryName below
// Your code here

Need a hint?

Constants use PascalCase and the const keyword.

3

Create a method with PascalCase naming

Create a method named DisplayBookInfo that takes no parameters and returns void. Inside the method, write code to print the bookTitle and authorName variables using Console.WriteLine.

C Sharp (C#)

string bookTitle = "The Great Gatsby";
string authorName = "F. Scott Fitzgerald";
int numberOfPages = 180;
const int MaxBooksAllowed = 5;
const string LibraryName = "City Library";

// Create method DisplayBookInfo below
// Your code here

Need a hint?

Methods use PascalCase and start with a capital letter.

4

Call the method and display output

Call the DisplayBookInfo method to print the book information.

C Sharp (C#)

string bookTitle = "The Great Gatsby";
string authorName = "F. Scott Fitzgerald";
int numberOfPages = 180;
const int MaxBooksAllowed = 5;
const string LibraryName = "City Library";

void DisplayBookInfo()
{
    Console.WriteLine(bookTitle);
    Console.WriteLine(authorName);
}

// Call DisplayBookInfo method below
// Your code here

Need a hint?

Just write DisplayBookInfo(); to call the method.
