Inside a chapter

Explain

With var, the compiler infers the type from the value. The type is still fixed.

var score = 95;

Build

Write a console calculator that reads two numbers.

double a = double.Parse(Console.ReadLine()!);
double b = double.Parse(Console.ReadLine()!);
Console.WriteLine($"Sum: {a + b}");
Console.WriteLine($"Difference: {a - b}");
Console.WriteLine($"Product: {a * b}");
Console.WriteLine($"Quotient: {a / b}");
$ dotnet run
10
5
Sum: 15
Difference: 5
Product: 50
Quotient: 2

Check

What type does score have?

In the back: useful commands, common compiler errors and fixes, quiz answers.

From the author

I wrote C# Fundamentals while teaching C# at the college level. The textbooks I could assign were expensive and not hands-on enough, so I wrote an affordable, practical book my students could keep beside them while they programmed. My classes used it for several years, and the college kept using it after I left.
