How to save my code?
 
Hello and Good Evening to everyone!

Situation:

I've written the following code in Vim (trying to write in C)

PHP Code:
#include<stdio.h
/* To prwto mou programma */
int main (void)
{
printf("Hello, world!\n");

return 0;
} 
And that's were I got stacked :P

I don't know how to save my file (example: hello.c)

(that's a classic example as you know :P)

I just don't get it..

Any help?

Thank you in advance :)

P.S: Here is a screen shot of my situation..

Vim is crazy. Once you get there, type ESC : wq and then press return

the ':' puts it in command mode

Heh ... welcome to LQ!


You need to find a vi tutorial or cheat sheet ;}


Code:
<ESC>:wq
will save your file and quit vim


Cheers,
Tink

Thanks!
 
Thank you both of you!

I finally got it :P

@Tinkster

Do you have any link to get a -really good- vim tutorial?

edit: I type the following command in terminal:

Code:
bobnos@ubuntu:~$ gcc hello.c -o hello.out
and I get this error:

Code:
hello.c:1:17: error: missing terminating > character
what is that and how can I fix it?

Thnx

For your include directive, you need #include <stdio.h>. The ">" at the end is missing. Really, though, the error message should have been sufficient - it even tells you the line number where the problem is!

Hi,

Welcome to LQ!

Learning vi - "cheat sheet" technique is a good tutorial that will show you how to use vi, a powerful visual editor.

:hattip:
The above link and others can be found at 'Slackware-Links'. More than just SlackwareŽ links!

You will soon learn that vim also has a heap a ways of doing things, but I just thought I would add that the following are equivalent:

Code:
<ESC>:wq

<ESC>:x

In addition to everything that has been said,
you might wanna try using an easier tool, such as Geany.

Thank you for your answers.

But I've still have a problem :p

I add > as someone told me before.

Then I wrote this code:

PHP Code:
gcc hello.c -o hello.out 
hello.out created but..

When I open it, nothing happen. Does anyone know why? :S

Please explain what you mean by "open"?

You should be executing hello.out:
Code:
./hello.out

gcc will just compile it to object code. I think he forgot the next step. It must be linked. The linker will insert some 'headers' in the object file telling the operating system where to find the entry point for the code and any parameters it may be passing.

alan99 06-10-2010 04:13 AM
Most systems will probably be using ELF as the executable format. a.out may not work on his system.

As for vi, typing
Code:
ZZ
will also save + quit, without the need for command mode.

For a good vi tutorial read A byte of Vim
