Fixed-size arrays

An array stores multiple elements of the same type in a single variable. Its size is fixed when created. Access elements using zero-based indices.

string[] clouds = new string[] { "wispy", "puffy", "grey" };
Console.WriteLine(clouds.Length); // 3
Console.WriteLine(clouds[0]); // wispy

foreach (string cloud in clouds) {
    Console.WriteLine(cloud);
}

How it reads

• string[] declares a variable that holds an array of strings
• new string[] { ... } creates the array with starting values
• clouds.Length returns the number of items in the array

Cloud tip: Since arrays have a fixed size, you cannot add or remove elements after creation. If you need a dynamic size, use List<T>.
