| 66 | <p>In our example, the first two lines of the function definition are the
|
|---|
| 67 | <em>header</em>. Its purpose is to state the function’s name and say how
|
|---|
| 68 | it is called:
|
|---|
| 69 | </p>
|
|---|
| 70 | <div class="example">
|
|---|

|
|---|
| 72 | fib (int n)
|
|---|
| 73 | </pre></div>
|
|---|
| 74 |
|
|---|
| 75 | <p>says that the function returns an integer (type <code>int</code>), its name is
|
|---|
| 76 | <code>fib</code>, and it takes one argument named <code>n</code> which is also an
|
|---|
| 77 | integer. (Data types will be explained later, in <a href="Primitive-Types.html">Primitive Types</a>.)
