I missed the "f" out of if :( ----- Original Message Follows -----
Hi All, Will someone please explain what I need to do to write and run a C program in the bash terminal.I think I may need to tell the terminal to run a c compiler. This is the outcome of a program I copied from a tutorial. john(a)sniffy:~$ #include <stdio.h> john(a)sniffy:~$ int main() bash: syntax error near unexpected token `(' I there is an easy to understand explanation I would like to hear it please.. Regards John

Hi, You can not just run a C program, C is not a scripting language as you appear to be trying to use it as, it requires you to first put the source code into a text file and then for it to be complied into an executable before you will be able to run it. Just doing a quick Google search came across this which may help: http://ce.uml.edu/compile.htm Regards, Steven -----Original Message----- From: wlug-bounces(a)list.waikato.ac.nz [mailto:wlug-bounces(a)list.waikato.ac.nz] On Behalf Of jaytee(a)clear.net.nz Sent: Sunday, 28 February 2010 4:10 PM To: jaytee(a)clear.net.nz; Waikato Linux Users Group Subject: Re: [wlug] C program.....

Hi John, You will also need to input the example into a file (preferably named with a .c extension) It looks like you initially tried to type in the commands directly into the bash prompt. Cheers, Wazza. On 28/Feb/2010, at 19:21 , John wrote:

In linux a program must be located in a directory located in the $PATH enviroment variable, or called be called directly with a directory, the most common way is ./a.out (./ being this directory)
Many thanks Ronnie that worked...Whooo whoo I am a programmer :) Regards John On Sun, 2010-02-28 at 19:56 +1300, Ronnie Collinson wrote:

Hi Bruce I am using gedit and have succeeded in getting the output I wanted from the program. I have got the veiw set to "c" but I guess that is just a human viewable thing and plain text would work just the same. Regards John On Sun, 2010-02-28 at 20:24 +1300, Bruce Kingsbury wrote:

I think someone recommended this to me a while back: http://crasseux.com/books/ctutorial/ Or it may have been another one like it. Anyhow yeah there are lots of tutorials online, was there one that you were looking at? What are you trying to accomplish anyway?
