Writing your first method

A method is a named block of work. You write it once and call it wherever you need it, which removes repetition from a program.

The parts of a method

private int AddTax(int price, int rate)
{
    int tax = price * rate / 100;
    return price + tax;
}

Reading the signature

• The return type says what the method gives back.
• The name says what it does, in a verb.
• The parameters say what it needs from the caller.

Methods live inside a class, so the natural next step is defining a class of your own.
