The body of the function

Display Figure 6.

There is a curly brace at the bottom of the edit pane that matches the one at the end of the function signature.

(The curly brace is not shown in Figure 6.)

Everything between that pair of matching curly braces constitutes the body of the function. 

Initially, that body is empty except for a return statement that will, by default, return the value 1.
