startingC: Learning the C Programming Language

Introduction

A Quintessential First Program

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

Loops & Conditionals

if then else

(switch) case (default - fall through)

while and for

break & continue

Arrays & Pointers

address, dereference address arith 2d arrays binary trees and linked lists - just give examples
