ReadMe File - Data Files These 22 data files are used by some of the example programs and by some of the problems from the Fourth Edition of Engineering Problem Solving with C by Delores M. Etter. The data files are text files so that they can be read from a C program. Within the text chapters, there are example programs that read information from data files. These 15 data files are included here. An additional 4 data files (rocket1.txt, rocket2.txt, rocket3.txt, suture1.txt) are included to accompany problems at the end of Chapter 3. The final three data files (two1.txt, two2.txt, two3.txt) are additional speech files that can be used with program chapter5_5. These files contain speech files for three different people saying the word "two".
