A Quintessential Start
OK, now that we have the example code, let's get cracking and run our first C program. First of all, move into the example directory:
cd startingC/examples/example1
We'll use of a Makefile for each example, so as to make the build process painless (hopefully!). All we need do is run make (see the [make tutorial about make] if you're interested in this further):
make
Now, we can run the classic program:
./hello.exe
and you should get the friendly response:
hello, world!
Bingo! We've just surmounted the hardest step in way--running our first C program. Given this quantum leap, everything else will boil down to the consideration of details, really.
Types
int char float double
short & long
sizeof() casting
enumerated types
The C Preprocessor
Loops & Conditionals
if then else
(switch) case (default - fall through)
while and for
break & continue
Functions & Header Files
Arrays & Pointers
address, dereference address arith 2d arrays binary trees and linked lists - just give examples
Structures
DAB again
watch out for padding
