The final line of the program is return 0;. In general the return statement has the effect that one might expect; it returns control to a calling function. In the case of how it is used here in main, it transfers control back to the operating system. An exit integer with a value of 0 is returned upon completion of the program. The fact that 0 is viewed as an integer is a consequence of the int designation that immediately precedes main. This is true more generally in that a function must return a value of the same type that appears in its definition with the exception of main functions and functions with return type void. The return statement could actually have been omitted from Listing 2.1 without causing compilation errors. The void return type will be discussed shortly.
C Programming

This cube() function is called twice in Figure 13.34. Figure 13.35 takes two parameters and returns no value. The keyword “void” as the return type indicates that this function returns no value. (In some programming languages, this form of module would be called a “procedure” rather than a function.) If the return type is left blank, rather than void, the C compiler assumes that a function returns int. That is not what is intended in this case.

A step is an instance of the Implementation class, which is an abstract class. It can be either a Service, User Input, or another Process. Services represent the Web Services in the Information System, User Inputs are descriptions of user choices on the front-end applications, and Processes can be composed with sub-processes. Implementations have names, inputs and outputs. For a Service, a name is the method’s name. The input represents the input arguments of the method, given as a dictionary from the argument name to the type of each argument. The output represents the return type of the method.
