This is an obsolete circa year 2001 page that deals with programming in C. Many of the links are old and broken.
- Is Clarity More Important Than Correctness?
- If your program is clear you can make it correct.
Can you be sure your program is correct if it isn't clear?

Daniel from Camp Nazareth out in Minnesota suggested this: The Many Languages of IT Programming
These first items are selected to be of use to people writing programs in the Algonquin environment in 1999.
This is made obsolete with the VALGRIND software under Linux.
You can make sure all your malloc/free function calls are matched by using the MEM software package. It replaces these C Library function calls: malloc, calloc, realloc, strdup, and free. Select here for details. You can pick up the software itself by selecting here.
Modern environments use valgrind to debug memory leaks.

The Internet is full of security incidents arising from code that forgets to check for buffer overflow. This is a serious programming error, and I don't accept student code that does not protect itself against overflowing its own internal buffers. Check the size of the buffer before you append anything to it!

Digest: CURMUDGEON'S EXECUTIVE SUMMARY
Buffer overflows appear to be the most common problems reported
in May, with denial-of-service problems a distant second. Many
of the buffer overflow problems are probably the result of careless
programming, and could have been found and corrected by the vendors,
before releasing the software, if the vendors had performed elementary
testing or code reviews along the way.
The International Obfuscated C Code Contest has some prime examples of how to write very confusing C code.
Once you think you understand loops and switch statements, see Duff's Device.
