Lecture 14 Objectives

At the end of today's class you should

KNOW:

why it is useful to be able to organize functions into libraries
which information should go into a header file, which information should go into an implementation file, and which information should go into an applications program

BE ABLE TO:

create a library of user-defined functions
draw a dependency diagram for a program that spans multiple files
create a makefile to manage a multi-file program

Sample Exam Question:

Create a makefile for a program that has two header files (board.h and useful.h), and three source files (board.c, useful.c, and game.c). The source files contain these include directives:

board.c:   #include "board.h"
           #include "useful.h"


useful.c:  #include "useful.h"


game.c:    #include "board.h"
           #include "useful.h"

(Hint: draw a dependency diagram first)
