    have the same type as the corresponding parameter.

    A declaration that also creates a usable entity.
    For example, a function with a function body that can be called.

floating-point:
    A type of variable (or value) that can contain fractions as well as
    integers. There are a few floating-point types in C++; the one we
    use in this book is double.

function:
    A named sequence of statements that performs some useful function.
    Functions may or may not take parameters, and may or may not produce
    a result.

initialization:
    A statement that declares a new variable and assigns a value to it
    at the same time.

parameter:
    A piece of information you provide in order to call a function.
    Parameters are like variables in the sense that they contain values
    and have types.
