--- 22 Nov 94 This is the code from the text "A Book on C," third edition, by Al Kelley and Ira Pohl, Benjamin/Cummings, Redwood City, CA, 1995 The code found here is meant for both UNIX and Macintosh environments. The same code, but with shorter filenames, occurs in the directory ../dos This code is appropriate for MS-DOS environments. The code is organized by chapter, and the filenames in each chapter directory are numbered to match their appearance in the chapter itself. For example, the files 10_nice_day.c 10_nice_day.in 10_nice_day.out in ch1 are all related. In this case, 10_nice_day.c contains a program. The following commands illustrate how the material can be used: cc -o nice_day 10_nice_day.c nice_day nice_day < 10_nice_day.in The last command should cause the contents of the file 10_nice_day.out to be printed on the screen. Where appropriate, files have been copied into a test program, and/or into a work directory. Consider, for example, the following related files in ch8: 1_cmp.c 1_fill.c 1_main.c 1_prn.c 1_test_qsort.c 1_test_qsort.out By concatenating the first four files, we created the program 1_test_qsort.c If we compile and run the program, we see the contents of the file 1_test_qsort.out printed on the screen. The ch8 directory also contains the subdirectory 1_wrk which contains the same program in a multi-file format, along with an appropriate makefile.
