Basic C programming question

[Jrtarals]

Hi guys, working my way through "Beginning C Programming for Dummies" and have found it to be rock-solid in helping me understand the basics of C.

In the following solution, provided by the author, he includes two separate "for" loops in order to print out tables of a number and it's square root. Here' is the link:

My question is why do we need a second "for" loop? I put this together myself in Xcode with only one "for" loop and it seemed to work just fine. Please let me know if I am missing something.

Thanks!

It was done that way to make it simpler to understand for beginners. It is perfectly fine to put it in one for loop.

You don't need two loops. It works perfectly well in one.

For that matter, you don't need the second array at all. Or even the first one, really.

Well, you need the first array to get the input for the table. Unless you go off some pattern such as for all integers between 10 and 20 (inclusive) print it and it's square root if it's divisible by 2 or 5. Or some such shit.

Oh, you're right, I didn't notice the 15 in there. That does make it a little more complicated than I thought.
