Statements

A C# program consists of many small statements. A statement is a single instruction to the computer — for example "print this text". Every statement ends with a semicolon ";".

Console.WriteLine("Hello, C#!");

The semicolon works like a period at the end of a sentence: it tells the compiler "this statement is complete, the next one follows". If you forget the semicolon, the compiler doesn't understand where a statement ends and reports an error.

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello!");
        Console.WriteLine("How are you?");
    }
}

Every statement in C# must end with a semicolon.

At its core, a C# program is nothing more than a sequence of such statements. The CLR processes them strictly in order — from top to bottom, one after another. At this point there are no "shortcuts" or jumps yet — it's purely step-by-step execution.

Which character marks the end of a statement in C#?

Statements don't just float around freely — they always sit inside a block enclosed by curly braces { }, for example the block of the Main() method. We'll see exactly how these blocks work in the next lesson.
