To complete the class-implementation process, you modify the C-language source-program template as shown in the following sample code. You must supply the code for each of the stubbed method procedures. In the example, "dog barking" is implemented as "printing the sound a dog makes," or, printing "Unknown dog noise." Because the C-library printf routine is used to implement this function, STDIO.H also must be included in the source program.
