Variables and types

C# is statically typed, so every variable has a type. Use int for whole numbers, string for text in double quotes, and bool for true or false. The keyword var lets the compiler infer the type for you.

int stars = 100;
string sky = "neon";
bool isClear = true;
var mood = "dreamy";

Console.WriteLine(stars);
Console.WriteLine(sky);

How it reads

• int stars = 100; declares a whole-number variable named stars
• string sky = "neon"; holds text, always in double quotes
• var mood lets the compiler infer the type from the value

Cloud tip: In C#, double quotes make a string and single quotes make a single char. They are not interchangeable.
