Document Summary
Lab 6: file i/o external data representation; fopen(), fclose(), fread() and fwrite(); struct practice. Setup: add the new directory "6" to the root directory of your working copy and repository. This will be the working directory for all the instructions below. A program"s working memory of stack and heap data structures only exists while the program is running. To store data between runs, and to capture output, we can use the filesystem. The filesystem is a service provided by the os that provides files to your programs. A file is like a named array of bytes, and once created a file will persist until deleted, even when the computer is turned off. You are familiar with files: text files like c sourcecode; sound files like mp3s; executable files like your compiled programs. At the filesystem abstraction level, these are all the same thing: just a contiguous sequence of bytes. The interpretation of these bytes is up to your program.
