macOS A noob needing help with C

[ETID]

Hello I've started a programming in C course for my engineering degree. At the moment I'm using Visual C++/C to do this but I was just wondering if there is a similar variant for mac as I prefer to work in OSX than XP.

Thanks for any help.

Every Macintosh comes with XCode, which comes with compilers for C, C++, Objective-C, Java, plus perl, python, ruby, and a few other languages.

Awesome. Is this located on the install disc?

 

[TygerMac]

Yes, it is on the install disc. Or you can download it from the Developers site at Apple. I just started C myself and xcode is great. If you find any good sites with tutorials or a good book, please let me know!

It looks gr8 but unfortunately I haven't been able to get even a simple hello world in C to work. I just get like 120 errors, have no idea what is going on.

If anyone does know of a tutorial site or similar that would be awesome

Give us some details and we might be able to solve the problem.

No details = no help in this forum I'm afraid.

right so I just want write a simple C code to begin with. I thought this was how I would go about doing it. Xcode>new project>blank project>new file>c file.

I then input this code in
/*hello world*/
include <stdio.h>
main()
{
printf ("hello world\n");
}

If that helps what I'm on about.

I'm used to using visual c++/C for this so I didn't really know what to do for some things. For instance where I regularly use (hash symbol)include etc. What do I do as macs don't seem to have a hash key

You main function should be int main (int argc, const char * argv[]).

Do not make a blank project.

Xcode > New Project > Command Line Utility > Standard Tool.

you are including a header file, does that header file exist?

Ah good eyes 🙂.

Yes look again at your include statement as well.

thanks got it working. Thanks to all you very nice people

I use Xcode every day for C/C++ programs and it's great. You can, however, also use the command line in Terminal. It's pretty simple.

cat > myprog.c
#include <stdio.h>
int main(void) { 
printf("Hello World!\n") ; 
return 0 ; 
} 
CTRL+D 

gcc myprog.c -o myprog 
./myprog

is all it takes. 😉

When doing this in terminal how would you get the hash for the #include <stdio.h> because I don't have one on my keyboard and even if I use a windows keyboard the hash key just turns into a backslash.

In UK Keyboard setup it's alt-3 to get a #.

Thanks for the alt-3 its a life saver! Since i started this thread I've already made so much progress.

cheers
