editing, compiling, running a C program
There are a number of methods;
discuss which ones you like and common practices.

int low = 17;

Look at your examples :
Then look deeper at types, sizeof(), pointers, struct using my code
in
C examples :
See how far we get, and continue Thursday with more C and
the bit/byte/int/data material in chapter 2.
Topics coming up:
- What does a C program spread over several files look like? How do you compile and run it?
- More examples of pointers, and how they connect with lists.
- C character and string data.
- Details of memory and data : int, long, hex, bits, bytes, and all that (chap 2 in text)
