Learning c, need a little help with compiling.

[jester.dev]

I am learning c through an online tutorial currently. And I
am running Linux, but the tutorial does not deal specifically
with linux. I'm not sure if I am compiling correctly or not
because I get errors when running the compiled program when
using: gcc hellow_world.c which created a file called hello.cs.
Now for some reason after deleting hello.cs I only get a file
called a.out when I compile which runs with no problems.

What's with the name a.out? From what I read from another tutorial, I was
supposed to get a file called helloworld that I could run, and not this
a.out file.

Thanks for your time,
Michael

That's the expected behavior. Whatever hello.cs was, as you've seen
it wasn't needed.
What's with the name a.out? From what I read from another tutorial, I was
supposed to get a file called helloworld that I could run, and not this
a.out file.

The name of the executable depends on how you compile it. If you want
it to be named helloworld, gcc -o helloword your_c_file_name_here.c
would do it.

Before you post further, check out the following links. This group is
for standard C only - Linux things, such as the idiosyncrancies of
gcc, should be posted elsewhere (I suggest comp.unix.programmer).

[m...]

for gcc, it will name the output file as a.out
if u want to name it use the -o parameter
eg
# gcc -o helloworld helloworld.c

enjoy it!

This is *completely* off topic, but we're all newbies at some point.

Read the man pages for gcc. Look at example code. Think of a little project
to do in c.

Learn to write Makefiles and autoconf scripts

For gcc, I reccomend the following cmd line options:

-ansi -pedantic -Wall -pipe -O2

As for learning c, there are two books for c u should buy, not borrow:

The C Programming Language (AKA K&R C) - Kerninghan and Ritchie
Efficient C Programming - Mark Allen Weiss

In general the weiss book is good for learning c, and k&r c is good for
reference.

best of luck!

Thanks everyone for the help. I'll be sure to read through
the FAQ, gcc manual and post in the appropriate group.
The tutorial I'm reading is based on the K&C book, but I
am still going to buy both.
