Understanding how to declare and initialize variables is a fundamental skill for any programming job.

1

Declare variables for book information

Declare a string variable called title and set it to "The Great Gatsby". Declare an int variable called year and set it to 1925.

C Sharp (C#)

# Declare the variables 'title' and 'year' with the given values
// Your code here

Use the syntax type variableName = value; to declare and initialize variables.

2

Add a variable for the author's name

Declare a string variable called author and set it to "F. Scott Fitzgerald".

C Sharp (C#)

Remember to use string type for text values.

3

Declare a variable for the book price

Declare a double variable called price and set it to 10.99.

C Sharp (C#)

string title = "The Great Gatsby";
int year = 1925;
string author = "F. Scott Fitzgerald";
// Declare the variable 'price' with the given value
// Your code here

Need a hint?

Use double type for decimal numbers.

4

Print all book information

Use Console.WriteLine to print the variables title, author, year, and price each on a new line.

C Sharp (C#)

string title = "The Great Gatsby";
int year = 1925;
string author = "F. Scott Fitzgerald";
double price = 10.99;
// Print the variables below
// Your code here

Need a hint?

Use Console.WriteLine(variableName); to print each variable.
