Example programs for/from the C programming language lecture

• tarball of all the example programs (including README and Makefile)
• README
• Makefile - to build all of the example programs
• arrays_ptrs.c - similarities of arrays and pointer references.
• command_args.c - accessing the command line arguments to a C program (when run from the Unix command line).
• count_char.c - simple character I/O and processing.
• count_char2.c - similar to count_char.c except that it uses a for loop instead of a while loop.
• filecopy.c - copies from stdin to stdout.
• filecopy2.c - similar to filecopy.c but using a more compact notation in which I/O and assignment are embedded in the test portion of a while loop.
• func_ptrs.c - passing "by reference" and the use of a pointer to a function.
• hello.c - "hello world" variant including an output decision based on user input as well as a basic function call.
• hello2.h, hello2a.c, hello2b.c - functionality of hello.c divided into separate modules (files) to demonstrate the use of #include files, and separate compilation.
• io.c - sample C I/O code provided as part of programming assignment #1.
• mem_mgt.c - structure definition, structure pointer declaration, allocation/deallocation of memory, and the dangers of careless pointer management/use. Note that this code contains examples of what NOT to do.
• struct_ptrs.c - the "->" shorthand for accessing the member of a structure via pointer dereference; demonstrates the importance of understanding operator precedence (includes a compilation error).
• swap.c - consequences of "pass by value" function arguments.

• temps.c, temps2.c, temps3.c, temps4.c - some simple, iterative, arithmetic processing and output.
