Execute a query and pull in one column of data
Process the data
Execute another query for another column
Process that data
etc...
Then take all the data stored in arrays and format it for display

Whereas his thinking seems to be

Execute a query to pull in all needed data from multiple tables
Process in one function and format for display

I guess maybe it just takes having a lot of familiarity with the language and you start to see the quicker way of doing things. His approaches also seem to be able to avoid the spaghetti logic I get myself into sometimes by nature of their compactness.
who is "he"?
if you described it to me, that means you too are thinking in that way...for describing it to me...SmilieSmilie
dont push yourself too hard...

no its not the language really, its the familiarity with the concept that you apply...the technical details can always be found in the documentation, concepts cannot.

Wow! Thank you everyone! As always unix.com comes through with some good insight. It's quite encouraging and inspiring. So I will press onward. I especially appreciated the suggestion that understanding the concepts if more important than understanding the language. That's been my approach to learning GNU/Linux to the point where I can use most distros fairly easily. I just need to do that with programming and maybe the jump from Bash to C will be mirrored in C to C++, PHP, Perl, Javascript and Java. (It might sound ambitious but I really want to get there) Now back to K&R C (this is the second edition which covers C89 ANSI C).

I got a nice simple response from a friend on another forum. (I can't be sure he didn't cheat and just post the answer from the K&R answer book, but I'll give him the benefit of the doubt)

Code:
int main()
{
    c = getchar();
    while (c != EOF)
    {
        putchar(c);
        do
        {
            c = getchar();
        } while ( c != EOF && c == ' ');
    }
    return 0;
}

Although I'm not yet used to the do-while construct, I can see where it works very nicely here. It checks the condition after executing the statements inside the loop. I think this is somewhat like Bash's do-until structure (although I've never used that). Just thought I'd share. Now onto the other problems in the chapter.
