So if I were to use terminal for the programs should
i just enter them the same as I would in XCode,
formatting and all?
Pretty much. You just need to make sure the files you save are plain text files. So you'd need a text editor that will save plain text files.
And is the "Hello World" message supposed to only
come up in terminal or should it be coming up in a
new window, like an alert type message?
Anything that's printed out will appear in the Terminal window. For example, here's a simple C program I typed into
TextWrangler:
<pre class="command">#include <stdio.h>
int main (void)
{
printf("Hello World\n");
return 0;
}</pre>If I save that in a text file called
helloworld.c, I can compile it like this from the Terminal (as long as I'm in the same directory):
<pre class="command">gcc -Wall -o helloworld helloworld.c</pre>To run it, I type this at the Terminal prompt:
<pre class="command">./helloworld</pre>And I get this on the next line:
<pre class="command">Hello World</pre>Once the program is done running, the command line prompt will show up again.
